Working, in the sense of producing a functional toolchain are both.

For --prefix=/usr you currently have to cope with a couple of minor
functional regressions due to defects/bugs/oversights in GCC and (not
yet having been mentioned) with quite an amount of bugs in rpm.

For --prefix=/opt you will have to cope with even more bugs/deficits in
rpm (RH's rpm does a poor job on packaging outside of /usr [1]).

Installing to /opt or /opt/<whatever> (We use /opt/rtems
or /opt/rtems-4.7 for the rtems.org packages) definitely is easier from
a pure packaging point of view, and if ignoring the problems rpm has.
