Stock Lua 5.1.5 provides a configuration knob to control usage of dlopen-based functionality. This is on by default when using LUA_USE_LINUX but is still a separate preprocessor symbol that can be manipulated separately.

In Elune, LUA_USE_POSIX is used as a single knob, which makes it difficult/impossible to compile Elune for POSIX while simultaneously disabling dlopen.

This is desirable for Elune installations that wish to statically link all dependencies, in particular to avoid a cranky linker warning, e.g.

/usr/bin/ld: /tmp/wowless.GKA9d8.ltrans4.ltrans.o: in function `unixDlOpen.lto_priv.0':
<artificial>:(.text+0x1218): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

Perhaps a separate configuration altogether is actually best, to uniformly (irrespective of POSIX or anything else) request the stub ll_ function implementations in loadlib.c.

elune/build/linux/bin/Release/lua5.1: (error object is a nil value)
stack traceback:
        [C]: in function 'error'
        (command line):1: in main chunk
        [C]: in ?

Found through the busted Lua unittest framework, which uses error() on exit.

From in-game testing the GC step multiplier is correct (200), however the pause value is incorrect (110 in-game, 200 in our config header).
