Add gcc3 directory in scripts

[Joel Sherrill]

After discussion with the SC, Ralf had this summary suggestion:

I have noticed that Joel has started to adapted the
scripts/gccnewlib/*.add to using gcc3. Actually, I am not convinced this
to be the right direction to head to, because gcc-3.0.x apparently still
is not as usable as one might want it to be.

IMHO, we need a means to support gcc2 and gcc3 in parallel.

Proposal:

• Add a gcc2 directory to scripts/ containing the contents of the

gccnewlib directory before the adaptions to gcc3.

• Adapt gcc2/*.add and gccnewlib/*.add to be able to build gcc2 and

gcc3-based toolchains.

• Additionally we might consider to rework parts of the rpm-specs to

allow parallel installation of gcc2 and gcc3 (In particular: separating
the gcc-drivers from gcc's support files)

Release:
RTEMS CVS

Environment:
NA
