description:
Implement sigemptyset() and sigfillset() not as macros but as inline
functions, just like the rest of the sigsetops.  From J.T.Conklin
in PR lib/25627; originally prompted to work around problems with
an application but also fixing one important bug: per POSIX, these
functions may be additionally implemented as macros, iff they evaluate
their macros only once.  This was not the case.
