As this will break existing ebuilds I'd suggest guarding it against
next EAPI. Out of top of by head the change will break at least
crossdev outright. At least for two reasons:
1. building a gcc cross-compiler usually refers to $SYSROOT/sys-include.
   'git grep sys-include' will show a bunch of ebuilds that create that
   symlinks outside the space.
2. cross-building target libc is currently done on the host's emerge
  and installs into /usr/$CTARGET/.

I think whitelist would be able to cover these use cases as they are
a function of ${CTARGET} (or $CATEGORY) value.
