libc: remove libc weak __pthreads_* wrappers
It is not possible to override for libpthread to override
the weak libc definitions. This has never worked in uclibc, and
does no longer work in glibc either (unless you use LD_DYNAMIC_WEAK).
The proper thing to do is have weak prototypes in libc, and
definitions in libpthread only. This way libc runs even if
those functions are not defined, but just needs to protect
against the NULL values (done by implementing __uclibc_maybe_call).
This fix the problems if libc is linked before libpthread or
if libpthread is pulled by a dependency library.
