Greetings,
The patch below is needed for google/integration branch:
we want to be able build libgomp.a with -fPIC, be able to link it into a
shared library, and be able to dlopen that library without running out of
static TLS space (-ftls-model=initial-exec precludes that last part).

Tested: make && make check
