Bug#1016363: libx11-6 1.8.1 also breaks glxinfo

[Hermann Meyer <brummer-@web.de>]

With libx11-6 1.8.1 I get:

glxinfo
name of display: :0
glxinfo: ../nptl/pthread_mutex_lock.c:424: __pthread_mutex_lock_full: Assertion `e != ESRCH || !robust' failed.
Abgebrochen

rebuilding libx11 with the --disable-thread-safety-constructor flag solved the issue.
