This package compiles the uclibc with __UCLIBC_HAS_THREADS__ enabled. As a
result, (at least) the following functions will be synchronized with a lock:

- malloc(), free(), ...
- atexit(), onexit()
- random(), srandom(), ...
- dns_lookup(), res_query(), gethostbyname(), ...
- fgetc(), fputc(), fputs(), vfscanf(), ...
