toolchain/crosstool-NG: fix bundled config files
Bundled config files have architecture-specific values in them, which may break if buildroot is configured with another architecture that does not forcibly set these option. For example, the bundled config files are for x86_64, and define: CT_ARCH_TUNE="generic" This comes from the BR2_GCC_TARGET_TUNE config option (in buildroot) that is set accordingly to the selected (arch,sub-arch). But if someone configures buildroot for, say, generic ARM, then the BR2_GCC_TARGET_TUNE config option is not set, and the crosstool-NG backend Makefile believes it should not be pushed down to the crosstool-NG config file. BUT... The crosstool-NG backend Makefile can not forcibly push BR2_GCC_TARGET_TUNE down to the CT-NG config file. If BR2_GCC_TARGET_TUNE is empty, the user can still set CT_ARCH_TUNE by running ctng-menuconfig. The backend Makefile already passes such values only if they are set. In the end, we can't push options as-is to the crosstool-NG config, but we MUST provide sane bundled config files, which this patch does. Signed-off-by: "Yann E.
