[Buildroot] [git commit] systemd: add option to enable compatibility libs

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=596b42f7d69be49558f9c791c952c9b669f80949
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Since systemd 209, some libraries have been merged into libsystemd.so:

 - libsystemd-daemon.so
 - libsystemd-id128.so
 - libsystemd-journal.so
 - libsystemd-login.so

A new configuration menu entry has been added to enable the installation
of compatibility pkg-config files, so that programs that depend on them
can still be built.

[Thomas: as suggested by Yann during the review, add an else clause
with --disable-compat-libs.]
