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.

(cherry picked from commit c56da4a4b0a36b1d6b03f0d3806e663a685fea70)
