Move aarch64-linux-gnu-gcc to depends rather than makedepends, since
it's a runtime requirement of musl. Drop aarch64-linux-gnu-binutils
because it's implicitly pulled in via gcc.
Thanks to AUR user @mtorromeo for pointing this out.
Oversight from the previous commit, thanks jahway603 on the AUR for
pointing this out. No version or release bump needed, just make sure
that future updates don't accidentally pull the old source.
