[Buildroot] [PATCH] alsa-utils: remove -ldl in static builds

[Baruch Siach]

Since commit ffd7a00aef723 (alsa-lib: add patch to remove hardcoded -ldl) we
patch alsa.m4 from alsa-lib to remove -ldl on static builds. autoreconf
alsa-utils to regenerate aclocal.m4 using our alsa.m4.

We also need to gettextize alsa-utils because we use a more recent gettext
version.

Fixes:
