[PATCH 5/5] gnu: Build lua-5.1 with dynamic library support and a dynamic library.

[Leo Famulari]

* gnu/packages/lua.scm (lua-5.1)[arguments]: Rewrite make-flags so that
  Lua is built with platform-specific instructions for shared library
  loading (dlopen).
* gnu/packages/patches/lua51-liblua-so.patch: Install liblua.so with
  execute bit set. Move "-fPIC" flag from patch to package definition.

+Subject: [PATCH] lua-5.1: Changes to Makefile patches
+
+Install liblua.so with execute bit.

 Patch the two Makefile to also create liblua.so
