It is supposed to provide the full path.  I suspect you have something
installed incorrectly, like maybe ld is missing from i686-pc-cygwin/bin
or you still have i686-pc-cygwin/bin in your path..  If the above is
true, then the cross version of gcc is using the linux (or whatever)
version of ld.  That's clearly wrong.

So, to be clear:  If i686-pc-cygwin-gcc is not returning a full path,
you have an installation problem.  You should fix that.
