Note that I dropped quite a few things related to CFLAGS: - the -mfsrra / -mfsca discovery was clean cmake and could have stayed; but kos-cc already passes those flags, so -ffast-math is enough to enable the FSRRA / FSCA instructions. - -fomit-frame-pointer is also a default option of KOS. - -fexpensive-optimizations, -finline-functions and -fstrict-aliasing were redundant as they are enabled by the optimization level specified. - -ffp-contract=fast is the default when using GNU C, which we are here.
