Fix uclibc handling and comment in GC_init_lib_bounds

(fix of commit ffd2f9fe0)

Issue #477 (bdwgc).

According to uclibc source it seems to have libpthread.so file,
unlike musl.  This commit replaces uclibc to musl in comment and do
not turn off the warning about missing libpthread.so for uclibc.

* malloc.c [REDIRECT_MALLOC && !REDIRECT_MALLOC_IN_HEADER
&& GC_LINUX_THREADS && __GLIBC__] (GC_init_lib_bounds): Change
uclibc (misspelled) to musl in comment; do not check whether __UCLIBC__
is defined.
