subdirectory in test-suite for target dependent scripts

I would like to add a subdirectory in test-suite called target and in that another subdirectory

so target/Mips

There are some scripts that possibly could be generalized but for now they are Mips specific and I would prefer that they be pushed upstream so that other people runnning test-suite for Mips have all the scripts they need for running qemu, etc. and running on target boards, etc.

Any objections?
