commit: https://git.buildroot.net/buildroot/commit/?id=d8dad069c861468b17397f01875b95e7375891d7
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

jit is enabled by default since version 3.0.0 on x86-64, i686, ARMv7 and
AArch64 targets however it raises the following build failure on ARM
with gcc 4.8:

jit.c:232:1: error: initializer element is not constant
 static const jit_gpr_t THREAD = JIT_V0;
 ^

This build failure was also reported with ARM on gcc 4.9:
https://www.mail-archive.com/guile-user@gnu.org/msg11497.html

So just disable jit with ARM and gcc < 5
