On mingw, even doing 'm4 --help | sed 1q' would result in
warnings about EINVAL, because mingw has odd pipe behavior
and doesn't fail with EPIPE when no one is reading the
other end. Gnulib works around most of this.
Meanwhile, strtol was marked obsolete in gnulib.
* gnulib: Update to latest.
* m4/gnulib-cache.m4: Import sigpipe module, drop strtol.

On mingw, I'm still seeing some EBADF when sending m4 output
to a pipe that exits early, and I'm trying to figure out if
that's still a glitch in gnulib, but this is better than
what we had previously in 1.4.16 so I'm pushing this now.
