# QEMU_EXTRAOPTIONS is not meant to be directly used, the extensions are

# In some cases (e.g. ppc) simply being arch specific (apparently) isn't good
# enough and a PACKAGE_ARCH specific -cpu option is needed (hence we have to do
# this dance). For others (e.g. arm) a -cpu option is not necessary, since the
# qemu-arm default CPU supports all required architecture levels.
