description:
disable use of ELF TLS in Mesa/libGL

this is an optimization that primarily benefits linux/glibc -
most other systems have this disabled. in netbsd we've tried to
patch around it to make things work, but there still appears to be
some edge cases where libGL mysteriously crashes.

discussed on tech-x11 some time ago. already in place in pkgsrc.
