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.

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.

libcompiler_rt: move file list to Makefile.inc for reuse elsewhere Also switch to the style used in the clang390-import branch to reduce future conflicts.

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. 2013-04-20 14:44:28 +00:00			`.if ${MK_INSTALLLIB} != "no"`
