optionrom: cope with multiple -O options

Reproducer:

CFLAGS="-g3 -O0" ./configure --target-list=aarch64-softmmu,arm-softmmu --enable-vhost-net --enable-virtfs

Here CFLAGS ends up with "-O2 -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 ... -g3 -O0"
and pc-bios/optionrom/Makefile forgets to add the -O2 it needs.
