kbuild: dwarf: use AS_VERSION instead of test_dwarf5_support.sh
The test code in scripts/test_dwarf5_support.sh is somewhat difficult to understand, but after all, we want to check binutils >= 2.35.2 From the former discussion, the requirement for generating DWARF v5 from C code is as follows: - gcc + gnu as -> requires gcc 5.0+ (but 7.0+ for full support) - clang + gnu as -> requires binutils 2.35.2+ - clang + integrated as -> OK Signed-off-by:Masahiro Yamada <masahiroy@kernel.org> Reviewed-by:
