[Buildroot] [git commit] opus: don't use assembly when on ARM, but without ARM instructions

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=d55c6b132e2f4835b6af6e5055c985ad5f715936
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The ARM assembly code in opus uses full ARM instructions, which won't
work on Thumb-2 only platforms such as ARMv7-M, so we disable the
assembly code in such situations.

Fixes:
