[Buildroot] [git commit] package/mc: Fix xlib_libX11 dependency

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=cb21cf5fb062e6d5da86f8844bc32078c1ed6cd1
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

On Peter´s autobuilder building mc fails:
http://autobuild.buildroot.net/?reason=mc-4.8.14

The reason can be found in
http://autobuild.buildroot.net/results/e25/e25587c17c2e8ddae83f9ed02541931f510bfcd6//build-end.log

checking for X... libraries /usr/lib, headers /usr/include

where configure picks up xorg libraries although no x11 stuff is enabled in the
defconfig used for this build.

This leads to subsequent errors visible in
http://autobuild.buildroot.net/results/e25/e25587c17c2e8ddae83f9ed02541931f510bfcd6//mc-4.8.14/config.log

mips64el-ctng_n64-linux-gnu-gcc: ERROR: unsafe header/library path used in cross-compilation: '/usr/lib'

causing most configure checks to fail afterwards. To fix the problem the mc
package should honour an optional dependency to the xlib_libX11 package.

Fixes
