[PATCH] Fix x86_64 libpthread

[Jakub Jelinek]

Hi!

The recent s390x patch backout reminded me that x86_64 has
/usr/lib64/crti.o in specs like sparc64. Wonder how libpthread works
on x86_64 then (it cannot) because __pthread_initialize_minimal cannot
be called when the standard crti.o is used to link libpthread.so.

gcc 3.2 will hopefully solve all this for good in gcc driver (see Alan
Modra's patch), but till then... This is what sparc64 does too to make
it work.
