This is a very old version of the linker.  We are now up to release 2.15...

Umm, this would appear to be invoking the linker via gcc.  I assume that 
you mean "./mips-elf-ld -T....." ?

If you add the "-v" switch to gcc's command line it will show you how it 
invokes the linker.  You can then see which libraries are being linked in.

Note - for some targets gcc will invoke a program called "collect2" 
instead of "ld".  This is a pre-processor program which is designed to 
help with the handling of constructors and destructors in C++ object 
files.  In most (non C++) cases however you can just substitute "ld" for 
"collect2" and obtain the same behaviour.
