Originally reported on Google Code with ID 297

The sanitized code failed with segfault when the libc.so is configured to support only
latest versions of symbols. The pthread_cond_init interceptor is trying to get the
symbol versioned as "GLIBC_2.3.2" while the libc.so has only "pthread_cond_init@@GLIBC_2.4"
symbol. 

What steps will reproduce the problem?
1. Configure and install libc.so with oldest abi support disabled.
2. Call pthread_cond_init 

What is the expected output? What do you see instead?
ASAN:SIGSEGV
=================================================================
==149==ERROR: AddressSanitizer: SEGV on unknown address 0x00000000 (pc 0x00000000 sp
0xbeac8b60 bp 0xbeac8b84 T0)

AddressSanitizer can not provide additional info.

What version of the product are you using? On what operating system?
gcc 4.8

In addition to this glibc may be built with unversioned symbols.

We need to pthread_cond interceptors from asan/msan.
Tsan does need them, but we don't have a good solution.
