+Subject: [PATCH] Fix build on mips64el
+
+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:
+http://autobuild.buildroot.net/results/f951d91d2ca4647170a52499a243d45d13d3bced/
