[PATCH] Fix build on mips64el

[Paul Cercueil]

The "cvt_offset" field may be used for anything non-ARM in
jit_fallback.c, so enable this field on anything non-ARM. Worst case
scenario, this field is not used and it only occupies 4 bytes of RAM.

Besides, when building for mips64el with the N32 ABI, the __WORDSIZE
ends up being 32 and not 64 (which may be a problem in itself), which
caused some more issues as the movi_d_w() macro referenced by
jit_mips.c was not defined anywhere.

This caused Buildroot's CI to fail when building on mips64el:
