so the user would do USE="cc-arm" to get an arm cross compiler ?

and then in the ebuild we'd have to do something like:
SLOT="cc-arm? ( blah )" ?
how'd would we specify a default slot ?

a few things / ideas ...
- you wouldnt merge the cross compiler to $ROOT, you would merge it to /
- it would be impossible to link against things in / since those libraries are 
of a different format
- i believe cross compilers have a diff linking / include / etc... path setup
- if we start supporting $LDFLAGS more, this will be easier :)
