[gobolinux-users] configure bug

[André Detsch]

The same happens on most KDE-* recipes. I'm using:
configure_options=(
   "--disable-libsuffix"
...
)

It seems to be the best way to do skip the problem.

PS: sorry for the late reply, I'm trying to catch up the list emails
after being away for about 2 weeks.
