Also compile A64 for quickcheck target

We don't run tests yet because even in release mode, this will take a
considerable amount of time.

Is it important to compile release _and_ optdebug? Wouldn't just optdebug be
enough to catch most compile errors? Remember the primary goal of quick check is
to be used by everybody, every time - coverage is secondary.

no, i don't think it's necessary, I just wanted to match the other platforms

File Makefile (right):

https://codereview.chromium.org/169303006/diff/1/Makefile#newcode362
Makefile:362: QUICKCHECKMODES = $(FASTTESTMODES),a64.release,a64.optdebug
No need for a separate "make" variable, and +1 for including only a64.optdebug:
I think the idea is that for the slow simulator-based architectures we do only
optdebug, while for the "native" platforms (=Intel) we run release, too.
