When using GNU ld on Solaris, a large number of asan tests SEGV, while Solaris ld is fine. This happens inside the __tls_get_addr interceptor, which is highly glibc-specific. Therefore this patch disables that interceptor.
Posted upstream at https://reviews.llvm.org/D141385. Tested on i386-pc-solaris2.11 and sparc-sun-solaris2.11. Ok to cherry-pick into libsanitizer?
