Hi,
This patch is supposed to fix PR59106
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59106).
The bug manifests when we link static sanitizer libs (asan, tsan or
ubsan) against pure C programs.
The patch adds -fno-rtti to LDFLAGS of sanitizer runtime libs (based on
Kcc's recommendation). This does not fix libubsan but it does not seem
to support static link anyway.
Tested against gcc asan testsuite on x86_64.
