Revert "x11/cde: Mark unbroken on i386"

x11/cde on i386 is broken on the package build infrastructure because
it cannot bind to a temporary of type va_list. Some users have reported
that they can build it by hand using ports however there is no solution
for the problem on the FreeBSD poudriere.

This reverts commit 25db2173606446697bb4b5b376420c492e1f549c.
