If we must do that... Can we get something in profiles a bit like this:

    USE_EXPAND_IMPLICIT="USERLAND KERNEL ELIBC ARCH"
    USE_EXPAND_UNPREFIXED="ARCH"
    USE_EXPAND_VALUES_USERLAND="GNU freebsd"
    USE_EXPAND_VALUES_KERNEL="linux blah"
    USE_EXPAND_VALUES_ELIBC="glibc"
    USE_EXPAND_VALUES_ARCH="x86 amd64 sparc mips blah"

so we've got an enforcable complete list of every legal value for
them, and less associated mess?
