Gentoo's xorg-x11 ebuild understands the USE flag "dlloader", which
enables this option:

x11-base/xorg-x11:dlloader - USE WITH CARE: Enable dynamic module loader (results in many unresolved symbols)

The most relevant portion of the ebuild file is:

	if use dlloader; then
		einfo "Setting DoLoadableServer/MakeDllModules to YES."
		echo "#define DoLoadableServer  YES" >> ${HOSTCONF}
		echo "#define MakeDllModules    YES" >> ${HOSTCONF}
		if use hardened; then
			echo "#define HardenedGccSpecs YES" >> ${HOSTCONF}
		fi
	fi

However, there appear to be other issues; search for "dlloader" in the
ebuild file for the specifics.

The X build system doesn't use a configure script. Configuration is
performed by creating a host.def file.
