uClibc_mutex.h and libc-lock.h

[Kevin Day]

Apparently with freetype, including #include <bits/libc-lock.h> causes
compile time errors.
The error has something to do with line 309 of bits/libc-lock.h where
the function __libc_cleanup_routine gets defined.
I simply commented out "#include <bits/libc-lock.h>" from
uClibc_mutex.h and freetype compiled properly.

I had related problems with compiling gettext as well but was able to
work around that.

The error was:
