libcompiler_rt: stop building with stack smashing protection libcompiler_rt implements certain functions that clang and gcc emit calls to as part of their codegen (e.g. for extended width math). Build it without stack smashing protection (SSP, -fstack-protector) in order to support building binaries without SSP, especially the dynamic linker. Besides, SSP is probably not very valuable in this library. Reviewed by: arichardson, dim, kib Sponsored by: Dell EMC Isilon Differential Revision: https://reviews.freebsd.org/D27786

Gcc has incompatible internal declarations for __divtc3 and __multc3 as defined in compiler-rt, but it has no option to silence its warning, so make gcc warnings for libcompiler_rt non-fatal. Noticed by: lwhsu MFC after: 3 days

Rename NO_WERROR -> MK_WERROR=no As suggested in D27598. This also supports MK_WERROR.clang=no and MK_WERROR.gcc=no to support the existing NO_WERROR.<compiler> uses. Reviewed By: brooks Differential Revision: https://reviews.freebsd.org/D27601

compilert-rt: build out-of-line LSE atomics helpers for aarch64 Both clang >= 12 and gcc >= 10.1 now default to -moutline-atomics for aarch64. This requires a bunch of helper functions in libcompiler_rt.a, to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel". (Note: of course you can use -mno-outline-atomics as a workaround too, but this would negate the potential performance benefit of the faster LSE instructions.) Bump __FreeBSD_version so ports maintainers can easily detect this. PR: 257392 MFC after: 2 weeks

Enable libcompiler-rt on MIPS. Originally we disabled libcompiler-rt on MIPS and SPARC64, because of an issue where __clzdi2 and __ctzdi2 would cause endless recursion. This bug has been fixed in r230021 already, but for some reason we only switched to libcompiler-rt on SPARC64 -- not MIPS. This means we can finally use <stdatomic.h> on all our architectures.
