Also a bit light on the commit message.

Thanks for enhancing the testsuite; as time-consuming as it is, it
always has a good payout in preventing regressions.

Should this be chmod +x?

I guess since you are sourcing the file, it doesn't matter if it the
helper file is executable; it is just division of labor.

s/source/./ (the spelled-out name is a bash extension not guaranteed by
POSIX).

fgrep is not standard (although it's likely to exist on all platforms
where qemu exists).  In isolation, [ doesn't need shell quoting
(although seeing quotes around a grep script makes it obvious what
pattern you are looking for).  I'd use either:

faked_cpu | grep -Fv '['
faked_cpu | grep -v '\['

Again, s/source/./
