[LLVMdev] spec tests + PWD=

[Chris Lattner]

Hi David,

It looks like you added the PWD= magic to Makefile.spec.  It is  
preventing me from running bugpoint on the desktop, with errors like  
this:

I think this comes down to SPEC/Sandbox.sh turning around and exec'ing  
its arguments, which include the PWD= line.  This is failing, but I'm  
not sure why (maybe it's because I'm using tcsh as my shell, not  
bash).  Is there a way to fix this without reverting the patch?
