configure: add macro to set arbitrary make variables
Add macro GIT_PARSE_WITH_SET_MAKE_VAR to configure.ac to allow --with
style options that set values for variables used during the make
process.
Arguments are the $name part of --with-$name, the name of
the variable to set in the Makefile (config.mak.autogen) and
the help text for the option.
