Right. Please read

Yesterday I fetched and built the latest llvm/compiler-rt in sparc64. I
could not manage (in a reasonable time) to get the stuff in
compiler-rt/lib/sanitizer_common and compiler-rt/lib/asan built: these
directories seems to be skipped when compiling on this platform. No, I
am not familiar at all with the llvm/compiler-rt build system. Also I
noticed that there are a lot of changes upstream since last gcc merge
that may or may not compile on sparc: basically constants and data
structures duplicating stuff from kernel headers.
Well, I really dont have time to hack the llvm build system and also
keep the upstream sanitizer compiling on sparc until next merge, sorry.
At this point I would suggest to either apply my patch to gcc's
libsanitizer to fix the sparc build until next merge[1] or disable
building libsanitizer on sparc targets.
[1] I offer my help to make sure that whatever comes in the next merge
builds on sparc64 in the gcc source tree.
