[git commit master] libc: add hidden calls to pthread cleanup funcs

[Mike Frysinger]

commit: http://git.uclibc.org/uClibc/commit/?id=e0ac4efbdb498319f03a2a95d75d061ab6c68491
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

A lot of libc code calls the pthread cleanup funcs implicitly (for stdio)
which currently goes through the PLT.  Since we already have forwarding
symbols for these funcs, it's safe to declare the internal libc usage
hidden as a loaded libpthread will have the real symbols found.
