use weak symbols for the POSIX functions that will be used by C threads

Browse Source 
The intent of this is to avoid name space pollution of the C threads
implementation.

This has two sides to it. First we have to provide symbols that wouldn't
pollute the name space for the C threads implementation. Second we have
to clean up some internal uses of POSIX functions such that they don't
implicitly drag in such symbols.
