That depends on the X11 release. Newer ones do, and most of the older
configure scripts failed on this one.

collect2 runs ld as a child process, and checks its standard output and
standard error. It's obviously crashing and not flushing the output and
you don't see it. Many years ago, there was a bug in freopen that 
caused an similar error; however, Chris Faylor, while still a netizen, 
fixed this way back, and besides, that code has been rewritten since.

An option is to get you a debugging copy, and you can run it under the 
debugger and get me the backtrace. Let me know if that'll work for you.

Highly likely.
