package/dbus: Add optional dependency to xlib_libSM
To detect X11 support dbus uses the autoconf macro AC_PATH_XTRA
http://cgit.freedesktop.org/dbus/dbus/tree/configure.ac#n1264
This macro checks for the optional presence of libICE:
http://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=blob;f=lib/autoconf/libs.m4;h=d2040d731f81fc1693e01d118c45d51ad169d56a;hb=HEAD#l472
quoting dbus configure with libICE not present:
checking for IceConnectionNumber in -lICE... no
quoting dbus configure with libICE being present:
checking for IceConnectionNumber in -lICE... yes
The binary usr/bin/dbus-launch is being linked to libICE and libSM if
the packages are available:
$ output/host/usr/bin/i586-buildroot-linux-uclibc-readelf -a
output/target/usr/bin/dbus-launch | grep NEEDED
0x00000001 (NEEDED) Shared library: [libdbus-1.so.3]
0x00000001 (NEEDED) Shared library: [libSM.so.6]
0x00000001 (NEEDED) Shared library: [libICE.so.6]
0x00000001 (NEEDED) Shared library: [libX11.so.6]
0x00000001 (NEEDED) Shared library: [libc.so.1]
To get a reproducable build add libSM as optional dependency to dbus,
libSM pulls in the dependency to libICE.
