minute-ia: set -O2 and omit frame ptr
There is a lot of unnecessary stack frame assembly being generated in the
final image. Turn up optimization to -O2 and omit the frame pointer.
BRANCH=none
BUG=b:122526004
TEST=verified the disassembly is much smaller and does not write register
to the stack all the time. Also loaded Arcada ISH5 with optimized image
and it boots fine.
