[PATCH] Clean pthread functions namespace for C11 threads

[Joseph Myers]

There are various places where this patch is missing a space before the 
'(' in calls to weak_alias.

I expect there are lots of other POSIX functions called from pthreads (and 
so called indirectly from C11 threads functions) where you'll need to move 
to calling implementation-namespace versions (which may or may not already 
exist) - will those be addressed in a later patch in the series?  (Adding 
threads.h to the headers tested for ISO11 in conform/, with corresponding 
expectations for header contents, will allow you to find such namespace 
issues through the linknamespace test results, but only once you actually 
have the C11 threads functions implemented.)
