	# Mainly, this is of concern if your arch is poor with GPRs, like x86.

	# Therefore both lua interpreter and compiler are statically linked to
	# the core library modules.

	# Note: This patch only adds the required targets to the makefiles
	# instead of relying upon libtool, which fails cross-compiling. Both
	# shared and static versions of lua libraries are installed.
