As could have been expected, the static libgo.a causes the same problem with hardware capabilities on Solaris/x86 as was solved for libgo.so withhttps://gcc.gnu.org/ml/gcc-patches/2016-12/msg00726.html Instead of trying to pass -mclear-hwcap with -static-libgo, it was deemed easier to solve both problems the same way and disable hwcaps support in the assembler in the first place. This has already been done in libstdc++, so I've moved the corresponding autoconf macro to config/hwcaps.m4 and adapted it to set HWCAP_CFLAGS instead of HWCAP_FLAGS to better differntiate from HWCAP_LDFLAGS. Everything else is straightforward, I believe. Bootstrapped without regressions on i386-pc-solaris2.1[02] with as/ld (where as supports -nH) and sparc-sun-solaris2.12 with as/ld (where as doesn't, or rather it's called -hwcap={1|0}), and the libgo runtime/pprof failure is gone. Ok for mainline?
I can't approve the whole thing, but moving the macro out of libstdc++ is OK.
