RE: Changes to g++.exp prevent testing multiple ABIs on irix

["Billinghurst, David (CRTS)" <David dot Billinghurst at riotinto dot com>]

I've started to look into this.  ld_library_path is set correctly in
g++_link_flags, and is reset to the correctly value when the abi changes.
The patch to set LD_LIBRARY<N32,64>_PATH to the same value as
LD_LIBRARY_PATH works. The problem is that LD_LIBRARY_PATH is not updated to
the new value of ld_library_path.

I have confirmed this by setting LD_LIBRARY_PATH to ld_library_path within
g++_link_flags.  I doubt this is an acceptable solution.
