Bug#1023330: x11 support missing.

[Zephaniah Loss-Cutler-Hull <warp@aehallh.com>]

After some investigation, it appears that the issue is that in 10.0.0 
--enable-dynamic silently fails at run time unless 
--disable-hidden-visibility is also passed to configure.

Note, this also breaks flpsed, which is what drove me to spend some time 
debugging this.
