It would be useful - even in just a testing capacity, as I'd like to
start doing test runs with a GCOV enabled skiboot so that we can get
code coverage data out of op-test-framework. However, building with GCOV
bloats the binary size to ~1.5MB - which isn't a problem on an FSP
machine, but is for OpenPOWER where we only have the 1MB partition. But
the xz compression will make this work.

Plus, we're getting close to the 1MB size anyway, and I'd prefer to just
compress it on flash (as this also speeds up boot time) than start
having config options to not build everything into skiboot (as this
enables developers/ODMs to get things horribly wrong).
