Makes more sense to have it here, and easier to change once we start
building host-glib.

$(comma) and $(space) are used in packages and the toolchain.

I often find myself forgetting what those targets were called, and I imagine
others may not even be aware of their existence.

Simply set SHELL to bash instead of adding CONFIG_SHELL to all shell
invocations. CONFIG_SHELL is still set, as it is used by kconfig.
|
|
It causes more trouble than it's worth, and we should move to building those
host tools ourselves to not get into version issues anyway.

This patch will add a rule to top level Makefile to depend on the
$(PROJECT_BUILD_DIR)/autotools-stamps as a required directory. Hence it will be
generated if missing in stead of made when the $(PROJECT_BUILD_DIR)/.root rule
is triggered.

This patch will create the autotools-stamps directory early in the build
process, thus making it possible for non Makefile.autotools.in packages to use
this directory to hold stamp files.

HOST_GLIB is set to the path that contains the host glib tool set and is
used when building packages using glib. The buildroot top level Makefile
sets HOST_GLIB using which to find the path where glib-genmarshal is
located.
The problem is that a cross compiled version of glib-genmarshal is also
put in the build_ARCH/staging_dir/usr/bin directory when the package
libglib2 is built. This cross compiled version will typically not run on
the host system.
Fix it by ignoring staging_dir in the which output.
Closes #5934
jacmet: fixed to work correctly if it's only found in staging_dir.

Improve external toolchain support
* Do not put kernel-headers in the dependencies of BASE_TARGETS in
the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers
are already supposed to be part of the external toolchain, so
there's no need to download, extract and install them.
* In the configuration system, don't display the kernel headers
version selection list when an external toolchain is selected. This
is implemented by moving the source
"toolchain/kernel-headers/Config.in" inside the if
BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2.
* Change the description and help message of the BR2_LARGEFILE,
BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in
toolchain/external-toolchain/Config.in. In the case of an external
toolchain, the semantic of these options is not to enable large
file support, IPV6 or RPC (since the toolchain is already compiled,
it has been decided previously). Their semantic is to let Buildroot
know about the characteristics of the external toolchain being
used.
As an improvement, we could guess these values automatically:
- for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in
bits/uClibc_config.h in the libc headers directory.
- for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the
same file
- for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in
the same file
- for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep
-- "--with-float=soft"
But I'm not sure how this would be possible, since these values are
used at configuration-time by other configuration options, not only
at build time.

make "make clean" remove the .root stamp, so that everything will
be reinstalled properly on a subsequent build. (bug id 4304)
Also remove new autotools-stamps directory.

The MAKELEVEL test is not that robust; It fails with the recent log
support or if buildroot is driven from an external Makefile.
Rework it to instead detect source-check/external-deps by the fact that
they set SPIDER.

If we ever want to support building out of tree, having the .config in the
tree is probably not what we want.

Provide kernel headers when ext toolchain is used, so we can compile
packages which need them.

There is not much point in deleting $(IMAGE) as the entire binaries dir
is removed. Furthermore, $(IMAGE) is a prefix rather than a file name.

Mark empty directories in target skeletons with .empty files
and remove them while copying to target (like it's already done for
svn and cvs files) to better support version control system which don't
handle empty directories (E.G. git-svn).
