Let pkg-config work with cross-compilers
In cross-compiler setups pkg-config often needs some help to
determine the correct libraries. This can be done for example by
setting PKG_CONFIG_LIBDIR to point to the directory where the
cross-compile .pc files are located. If PKG_CONFIG_LIBDIR was not
set already outside of the Makefile we set it according to LIBS_BASE
and add the respective path to the linker's rpath. This makes it
possible to easily cross-compile by only setting CC and LIBS_BASE on
the command line.
This patch also removes the explicit default for LIBS_BASE again
because it does not play well with this change and was a bad idea to
begin with.
Corresponding to flashrom svn r1876.
