[libvirt] [PATCH] build: fix example build on MacOS X

[Eric Blake]

Partial reversion of commit 76d87a59, now that bootstrap is smarter.

* .gnulib: Update to latest, for poll and bootstrap fixes.
* bootstrap: Resync from gnulib.
* autogen.sh: Drop redundant tool checks; bootstrap does them
better, by honoring environment variables.
* examples/domain-events/events-c/Makefile.am (INCLUDES)
(event_test_LDADD): Use gnulib library during build.
* bootstrap.conf (gnulib_tool_option_extras): Revert --libtool
addition, now that updated bootstrap does it for us.
Reported by Justin Clift.

>> OSX MacPorts has libtool named as glibtool, with libtoolize
>> named as glibtoolize.  This patch adds support for this, and also
>> adds a check for pkg-config, to warn when it is missing.

>Hmm - would it be easier to make bootstrap.conf list pkg-config as a
>prerequisite, rather than having to hack up autogen.sh to do that?

Now done, and verified with Justin on IRC (although double-checking
with this exact patch before giving an ACK wouldn't hurt).
