In order to backport commit d5c8d6e0fa61 ("kbuild: Update assembler calls to use proper flags and language target") to resolve a separate issue regarding PowerPC, the problem noticed and fixed by commit 80a20d2f8288 ("MIPS: Always use -Wa,-msoft-float and eliminate GAS_HAS_SET_HARDFLOAT") needs to be addressed. Unfortunately, 6.1 and earlier do not contain commit e4412739472b ("Documentation: raise minimum supported version of binutils to 2.25"), so it cannot be assumed that all supported versions of GNU as have support for -msoft-float. In order to switch from KBUILD_CFLAGS to KBUILD_AFLAGS in as-option without consequence, move the '-Wa,-msoft-float' check to cc-option, including '$(cflags-y)' directly to avoid the issue mentioned in commit 80a20d2f8288 ("MIPS: Always use -Wa,-msoft-float and eliminate GAS_HAS_SET_HARDFLOAT").
