Log message:
gobject-introspection: Exclude system paths from LD_LIBRARY_PATH.

During builds, g-ir-scanner sets LD_LIBRARY_PATH in the environment for the C
compiler, with a path set for every -L argument passed to it.  This can cause
problems when system paths are added but the compiler is trying to link against
libraries that have built against pkgsrc libraries, as LD_LIBRARY_PATH has a
higher precedence than the RUNPATH built correctly into the libraries.

Fixes issue seen on SunOS where /usr/lib/libgcc_s.so was selected ahead of the
correct GCC library built into the cairo libraries during a build of pango.

Bump PKGREVISION.
