[PATCH] Fix missing err declaration in __pthread_initialize_minimal_internal

[Steve Ellcey <sellcey@imgtec.com>]

Roland's patch (https://sourceware.org/ml/libc-alpha/2015-05/msg00464.html)
to set tid field to a unique value removed the declaration of err
[INTERNAL_SYSCALL_DECL (err);] from __pthread_initialize_minimal_internal,
but there are other uses of err in other INTERNAL_SYSCALL's in
__pthread_initialize_minimal_internal so this broke the build glibc build
for MIPS (and presumably other platforms).

Here is a patch to put the declaration back.  I think the only question
is exactly where this declaration should go.   I initially put it right
in front of the first INTERNAL_SYSCALL call but I noticed that that is inside
of an ifdef and there are other INTERNAL_SYSCALL uses (with err) that
are in different ifdef's so I moved the declaration outside of any ifdef's.
This fixed my build problem.  OK to checkin?
