build: update to latest gnulib

It's been a while, and we're between releases, so now's as good
a time as any to resync.  This also fixes a build-breaker on
cygwin, where cygwin 1.7.11 introduced a header bug in <termios.h>.

* .gnulib: Update to latest.
* bootstrap: Resync.
* cfg.mk (sc_prohibit_strncmp): Copy upstream changes to
sc_prohibit_strcmp.
