ModemManager patches to fix build warnings

[Aleksander Morgado <aleksander lanedo com>]

Hi all,

Find attached some patches which fix the warnings issued when
bootstrapping the ModemManager project (0001 and 0002); as well as some
other minor autotools things (0003 and 0004).

One of the patches (0002) needs to bump the autoconf requirement to
2.60; which shouldn't be a big issue.

Cheers,

Subject: [PATCH 1/4] build: fix automake portability warnings

Makefile.am uses several GNU gcc extensions. -Wno-portability will avoid
emiting portability warnings during bootstrap.

Subject: [PATCH 2/4] build: require autoconf 2.60 and fix warnings

AC_GNU_SOURCE is deprecated, AC_USE_SYSTEM_EXTENSIONS (introduced in
autoconf 2.60) should be used instead.
