Bug 3456

Fix:
add "-lpthread" to *link options in specs file.

State-Changed-From-To: open->suspended
State-Changed-Why: The release notes for GCC at http://gcc.gnu.org/install/specific.html#mips-sgi-irix6
    say the following:
    
    "The --enable-threads option doesn't currently work, 
    a patch is in preparation for a future release."
    
    I don't know what the status of the patch is, but
    basically --enable-threads option does not work on IRIX.

 Hello,
 
 this bug report deals with the inavailability of thread support on Irix  
 6.5, as mentioned in the target specific install instructions. Does  
 anybody know how current this statement is? Is such support still  
 lacking? Does gcc 3.3 still exhibit this problem? Thanks,
 
 Dara

I just looked in the source and the LINK_SPEC does not have -lpthread in there at all so thi is not 
fixed at all.

Working on a patch.
