C compiler cannot create executables

[Amalaye Oyake]

I was rebuilding RTEMS and I was running into this problem:

checking for C compiler default output file name... configure: error: C
compiler cannot create executables. 

I am assuming that configure was using the cross compiler tools that I built
... it seemed to build everything else just fine, but kept getting hung here
~ pc386/configure failed for pc386.
