That looks a bit dubious to me.  If this is relying on some uclibc
implementation detail then I think it should either be applied for
uclibc only, or guarded with something like "#if defined(__UCLIBC__)
&& !defined(sigmask)".  Otherwise you might end up trying to call
__sigmask() on non-uclibc systems which could have unwanted effects.
