glibc 2.2 should support MIPS - for details check my homepage

Use readelf from binutils current to check what's in the executable.

You don't add the dynamic linker here.  See how gcc calls ld with gcc
-Wl,-v  or with gcc -v.

Or your cross tools are not configured correctly.

You better ask on one of the MIPS lists for help.
