libsanitizer: Fix asan SEGVs with gld on Solaris

Browse Source 
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.
