2011-07-25toolchain: add user defined target LDFLAGS optionsBaruch Siach
Allow the user to specify additional options for the target LDFLAGS. I use this to pass the -te500v2 option to the linker, when using the CodeSourcery toolchain for PowerPC. This chooses the correct CRT for e500 hard float. Otherwise I get errors like undefined reference to `_save32gpr_31' undefined reference to `_rest32gpr_31_x' at final link time.

2011-06-12toolchain: introduce BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDSThomas Petazzoni
Unfortunately, the official Blackfin toolchains are built without the shadow password support, so our default Busybox configuration fails to build. Therefore, we introduce a new hidden knob BR2_TOOLCHAIN_HAS_SHADOW_PASSWORDS, which is set to yes for Buildroot internal toolchain, for toolchains generated by the Crosstool-NG backend, for Glibc external toolchains and for Uclibc custom external toolchains. It is left unset by the Blackfin toolchain profile. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2011-01-15toolchain: add a USE_MMU build optionMike Frysinger
Some packages need to know whether the MMU is in play, so add a toolchain option to expose the feature to them.

2010-12-13toolchain: BR2_NEEDS_GETTEXT must be y when uClibc is usedThomas Petazzoni
BR2_NEEDS_GETTEXT was already set to y for Buildroot internal toolchain and external toolchains based on uClibc, but wasn't set for toolchains based on uClibC built by the Crosstool-NG backend.

2010-12-13toolchain: rework thread optionsThomas Petazzoni
The selection of linuxthreads, linuxthreads old or NPTL doesn't make a lot of sense for external toolchains. So, instead, we : * Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be selected by toolchain specific options when thread support is available. Package needing to test thread support should use this option. * Move the none/linuxthreads/linuxthreads old/NPTL selection to Buildroot internal toolchain configuration. * Add an option in external toolchain to tell if thread support is available or not in the external toolchain. We assume that glibc without threads is not possible, as Ulrich Drepper said in http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html ffmpeg, dmalloc and openvpn are fixed to use the new BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix is no longer used, as the configure script doesn't even understand this option.

2010-12-13toolchain: move Stack Protection Support optionThomas Petazzoni
The BR2_USE_SSP option is only used inside the uClibc build, so only meaningful for Buildroot internal toolchains. Therefore, the option is moved to the right location so that it isn't visible when working with external toolchains.

2010-12-13toolchain: rework C++ optionsThomas Petazzoni
Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with BR2_GCC_CROSS_CXX not being visible (and therefore being useless), let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain and install C++ libraries on the target. We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden option, which is selected by an option in Buildroot toolchain support or an option in External toolchain support, just as we did for other toolchain features. Some work definitely remains to be done : - The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the moment in order to avoid changing all packages. - We should clarify the other language-related options (Fortran, Java, Objective-C, etc.).

2010-12-13toolchain: Improve C library option selectionThomas Petazzoni
Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR, BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options. Then, for Buildroot toolchains, external toolchains and Crosstool-NG toolchains, provide visible options that selects the hidden options. This allows : * To show a different label and help text in the case of Buildroot toolchain (do you want to enable feature X ?) and in the case of external toolchain (is feature X available in your toolchain ?) * To not show any option when a glibc external toolchain is selected (since glibc is assumed to support all of largefile, IPv6, RPC, WCHAR, locale and program invocation) and have them all selected in that case. There is some amount of duplication between Buildroot toolchain config options and Crosstool-NG toolchain config options, because kconfig doesn't allow to source the same Config.in file twice (even if under mutually exclusive conditions). This duplication is more readable that the hack that consists in splitting files in multiple pieces. However, this commit changes the name of the options visible in the configuration interface, so existing .config files will have to be updated accordingly.
