How did you copy it?   You have to use cp -a or tar or mv;
plain old cp will screw up symlinks.

Also, perhaps the tools you're building are old enough that
they don't support being relocated after they are built.
If that's the case, then you can use
http://kegel.com/crosstool/current/fix-embedded-paths.c
to fix up the embedded paths after the move -- as long as the
new absolute path is shorter than the original.
See crosstool.spec.in for an example of its use.

I haven't run into that myself, possibly because I've never built
an rpm for gcc-3.3.3.
