-Wa,-msoft-float is tested with as-option, which will be a problem for clang with an upcoming change to move as-option to use KBUILD_AFLAGS instead of KBUILD_CFLAGS due to a lack of '-mno-abicalls' in KBUILD_AFLAGS at the point that this check occurs; $(cflags-y) is added to KBUILD_AFLAGS towards the end of this file. clang: error: ignoring '-fno-PIE' option as it cannot be used with implicit usage of -mabicalls and the N64 ABI [-Werror,-Woption-ignored] This could be resolved by switching to a cc-option check but '$(cflags-y)' would need to be added so that '-mno-abicalls' is present for the test. However, this check is no longer necessary, as -msoft-float is supported by all supported assembler versions (GNU as 2.25+ and LLVM 11+). Eliminate GAS_HAS_SET_HARDFLOAT and all of its uses, inlining SET_HARDFLOAT where necessary.
