The problem here is, that such a test can only be done in libs/luajit/,
whereas --disable-luajittex has to be specified at the top-level, in
texk/, or in texk/web2c/.

As for your problem with clang, please try

   $CC $CFLAGS -E lj_arch.h -dM | grep '__i386\|_M_IX86'

with different values for CC and CFLAGS until __i386, __i386__, or _M_IX86
is defined.

=========

Please also look into libs/luajit/config.log for:
    checking for architecture
and tell me the result.  This should be either
    Darwin x86 x64
or
    Darwin x86 x86
