FYI: [PATCH] gnulib: update gnulib submodule.

[Gary V. Vaughan]

Applied as obvious, to collect some bug fixes and move one of
our local gnulib patches upstream where it belongs.

Among others, this fixes a bug in _build-aux expansion so that
`make syntax-check' works again.
* gnulib: Updated to todays master HEAD revision.
* gl/top/maint.mk.diff: Remove. This patch has been applied
upstream already.
