B20.1: make dependencies broken

[Kevin Wright]

I agree your make file works.  However your makefile lives in the target
directory and copies files from another directory to the target directory.

My makefile lives in the source directory and copies files to another
directory.  This is (I would have thought) the more normal use of make i.e.
creating a file from a source file and then copying it to an installation
directory.

My make file works on 5 different flavours of Unix using gnu make version
3.75 and 3.76.1.   It worked on B17 using gnu make 3.75.  It doesn't work on
B20.1 using gnu make 3.76.1 as supplied with B20.1 binaries.
