Because I install gcc into /usr/app/gcc-N.N.N-target/{bin,lib,whatever}
and then I create links for every binary in bin/*
/usr/bin/foo -> /usr/app/gcc-N.N.N-target/foo
Same for lib/* etc.
I do it not not only for gcc but for almost everything.
I discovered that a lot of packages will "remember" patchs given
to configure and use those at runtime. I want them to use
/ust/bin/something rather than /usr/app/bar/bin/something.
I found that usually giving bindir=/usr/bin to configure
but giving bindir=/usr/app/bar/bin to "make install" will do the trick.

Yes, I see... I will try giving bindir=/usr/app/gcc-N.N.N-target/bin
to configure. Will let you know if it still doesn't work.

Maybe gcc can use paths relative to executable's location?
readlink("/proc/self/exe") and all that.
It will make gcc installation movable without rebuilding.
(Actually it's my biggest gripe about the way Linux packages
are built: generally you can't move them
and expect them to work).
