[svn-r3406] Purpose:
    Fixlet
Description:
    FIxed the hack for the INSTALL macro. It was checking the "whole"
    path to the install-sh script instead of if it was just a relative
    path with install-sh at the end.
Solution:
    Changed the test to match any relative path with install-sh at the
    end. This assumes that the install-sh is the one we supply to them
    (an assumption it was making before, really).
Platforms tested:
    Gondolin, Linux
