Use CFLAGS_NO_SIMD in preference to varying lists of -mno-xxxx flags. Go ahead and defined -D_STANDALONE for all targets (only strictly needed for some architecture, but harmless on those it isn't required for). Also add -msoft-float to all architectures uniformly rather that higgley piggley like it is today. Differential Revision: https://reviews.freebsd.org/D3496 2015-08-27 23:46:42 +00:00			`# $FreeBSD$`

Add -fPIC to the standalone build flags on arm64. This is needed as loader.efi is position independend, however we were not building it as such causing a build failure when building with lld. Sponsored by: DARPA, AFRL 2017-04-07 14:30:51 +00:00			`CFLAGS+= -fPIC -mgeneral-regs-only`
