I don't think that's enough. This would generate GCC executables
polluted
by things in current system. For example,

    /media/sda2/usr/libexec/gcc/{version}/cc1

may link to

   (in sda7) /usr/lib/libgmp.so

But actually there may be no /media/sda2/usr/lib/libgmp.so. So when you
try to invoke GCC in /dev/sda2, you'll receive

    error while loading shared libraries: libgmp.so: cannot open shared
    object file: No such file or directory

That's bad. I suggest to chroot into /media/sda2.
