What about trying to compile the following chunk of code from
lj_arch.h (possibly simplified or possibly trying to compile the whole
file since there are other tests further on) as a test in ./configure
script?

#if defined(__i386) || defined(__i386__) || defined(_M_IX86)
#define LUAJIT_TARGET LUAJIT_ARCH_X86
#elif defined(__x86_64__) || defined(__x86_64) || defined(_M_X64) ||
defined(_M_AMD64)
#define LUAJIT_TARGET LUAJIT_ARCH_X64
#elif defined(__arm__) || defined(__arm) || defined(__ARM__) || defined(__ARM)
#define LUAJIT_TARGET LUAJIT_ARCH_ARM
#elif defined(__ppc__) || defined(__ppc) || defined(__PPC__) ||
defined(__PPC) || defined(__powerpc__) || defined(__powerpc) ||
defined(__POWERPC__) || defined(__POWERPC) || defined(_M_PPC)
#ifdef __NO_FPRS__
#define LUAJIT_TARGET LUAJIT_ARCH_PPCSPE
#else
#define LUAJIT_TARGET LUAJIT_ARCH_PPC
#endif
#elif defined(__mips__) || defined(__mips) || defined(__MIPS__) ||
defined(__MIPS)
#define LUAJIT_TARGET LUAJIT_ARCH_MIPS
#else
#error "No support for this architecture (yet)" #endif

If the compilation fails, simply --disable-luajittex. There are
zillions of attempts to compile different chunks of code as part of
./configure, so why not testing for additional one and spare people
some pain?

That change would make me really happy: people wouldn't need to
bother/remember to switch luajittex compilation off.
