Compilation x11/libX11 fails with panic

[Ulrich Grey]

I had read the posting from Jürgen Weiss.
Hence I had disabled superpages.

Here are the settings during the crash:

root at quad:~ # uname -a
FreeBSD quad 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r274634M: Tue Nov 18
00:44:36 UTC 2014
gwgpi at quad:/usr/local/DEVEL/obj/usr/local/DEVEL/SRC/head/sys/WANDBOARD-QUAD
arm 

root at quad:~ # sysctl vm.pmap.sp_enabled
vm.pmap.sp_enabled: 0
