Log Message:
Introduce a BUILD_USES_X11 definition, defined in package Makefiles,
and used to denote that a package uses X11 headers and libraries to
build, but does not install itself into X11BASE (xpkgwedge
notwithstanding).

This is used to ignore packages which would otherwise cause build
problems on machines with no X11 installation.
