 FYI, I'm still getting a failure here, with:

$ mips64el-linux-ld --version
GNU ld (GNU Binutils) 2.20.1.20100303
[...]
$

-- so this is a plain upstream development snapshot as these have their 
date appended.  Can we just get rid of the subversion components beyond 
the third, as I already suggested?  I.e. stop on the third point and in 
any case on a non-point-non-digit.

 I'll post a minimal fix shortly, feel free to enhance it if needed.
