When developing a patch I frequently sit in a cycle like this:

<edit edit edit>
$ make cc1
$ make check-gcc RUNTESTFLAGS="only/the/subset/I/care/about.exp"
FAIL: ...

<repeat>

I would not mind much if final acceptance testing for patches was done
on an installed tree, but I'll be unhappy if you break the above.
