Subject: include/plan9: make mklibc.rc compatible with 9atom
X-Git-Tag: go1.3beta1~14

include/plan9: make mklibc.rc compatible with 9atom

Since there is no Runemask constant in UTF-8 enum in
9atom, removing the other constants leads to an empty
enum, which is illegal. Thus, we remove enum entirely.
