# Using dynamic linked lua is not recommended for performance
# reasons. http://article.gmane.org/gmane.comp.lang.lua.general/18519
# 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.
