gcc-3.3.3, when it comes out, will have that nice relocatable property
you want.  Until then, the thing to do is to set PREFIX before running all.sh or crosstool.sh
to point to where you want the compiler to end up.

Although this is clear enough if you actually read the shell scripts,
a lot of people have had the same question, so in the next release
I'll make it more obvious.
