The dynamic library loader (-ldl) generally doesn't work with
static builds (some toolchains give you a warning if you try).
That is a known limitation and not specific to LuaJIT.
To work around this: set LJ_TARGET_DLOPEN to 0 in src/lj_arch.h.
And yes, this means you lose the ability to load any kind of
C module at runtime with require().
