Allow building zlib outside of the source directory.
To build, simply run configure from the source directory by
specifying its path. That path will be used to find the source
files. The source directory will not be touched. All new and
modified files will be made in the current directory. Discovered
in the process that not all makes understand % or $<, and not all
compilers understand -include or -I-. This required a larger
Makefile.in with explicit dependencies.
