PR sanitizer/67899 is a bootstrap failure on sparc-linux, caused by a
compilation error in libsanitizer.
The root cause is that `struct sigaction' has changed layout in glibc
twice recently, first an unintended ABI change in glibc-2.20, and then
the correction in glibc-2.22 (backported to the .20 and .21 branches).
(See glibc bz#18694). Around the time of the first change, libsanitizer
was changed to match, but it wasn't updated for the correction. The end
result is an ABI mismatch and assertion errors during compilation of
libsanitizer. (The sa_flags field is of the wrong size and at the wrong
Fixed by adjusting the SPARC part of libsanitizer's sigaction struct
to match glibc (except for the broken .20 and .21 initial releases).
Tested w/o regressions on sparc-linux-gnu (post-2.20 glibc), x86_64-linux-gnu,
powerpc-linux-gnu, armv7l-linux-gnueabi, and m68k-linux-gnu.
Is this Ok for trunk and 5/6 branches?
