[Buildroot] [git commit] vo-aacenc: disable arm optimizations on thumb2-only variants

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=513a6a56361de32bb6969659a0b34c516cd3135e
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The ARM assembly optimizations in vo-aacenc requires ARM instructions
support, so disable for ARM variants without ARM instruction support (E.G.
cortex-m).
