Alyssa Ross 665732d877 lua: fix linkage
This fixes a couple of problems:

 * Lua 5.1 doesn't have SYSLIBS, so wasn't being linked with any
   libraries.

 * SYSLIBS doesn't include -lm, so we had to add that manually to
   pkgconfig.  LIBS includes -lm, so we don't need that hack any more.

longDescription = ''
Lua combines simple procedural syntax with powerful data
description constructs based on associative arrays and extensible
semantics. Lua is dynamically typed, runs by interpreting bytecode
for a register-based virtual machine, and has automatic memory
management with incremental garbage collection, making it ideal
for configuration, scripting, and rapid prototyping.
