There's not much sense in doing that because if user or his build-system didn't set CROSS_COMPILE we still may very well make incorrect guess. But as it turned out setting CROSS_COMPILE is not as harmless as one may think: with recent changes that implemented automatic discovery of __host__ gcc features unconditional setup of CROSS_COMPILE leads to failures on execution of "make xxx_defconfig" with absent cross-compiler, for more info see [1]. Set CROSS_COMPILE as well gets in the way if we want only to build .dtb's (again with absent cross-compiler which is not really needed for building .dtb's), see [2]. Note, we had to change LIBGCC assignment type from ":=" to "=" so that is is resolved on its usage, otherwise if it is resolved at declaration time with missing CROSS_COMPILE we're getting this error message from host GCC: | gcc: error: unrecognized command line option -mmedium-calls | gcc: error: unrecognized command line option -mno-sdata [1] http://lists.infradead.org/pipermail/linux-snps-arc/2018-September/004308.html [2] http://lists.infradead.org/pipermail/linux-snps-arc/2018-September/004320.html Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com> Cc: Rob Herring <robh@kernel.org> Signed-off-by: Vineet Gupta <vgupta@synopsys.com> |
