EABI specifies thumb; however, it's possible to have code which
conforms fully to EABI but does not rely on the presence of thumb. GCC
is incapable of generating such code, but it could be enhanced to do
so, and all of the existing assembly in musl is plain-v4-compatible,
so I would prefer not to shut out the possibility of supporting older
ARM.
