using --disable-manpage-support it's finally possibly to disable the formerly obligatory use of a2x to generate the manpage documentation. this is the final solution to the decade old problem that users need to install the enormous asciidoc package to compile TINYproxy from source, or otherwise get a build error, even though the vast majority is only interested in the program itself. solution was inspired by PR #179. closes #179 closes #111 note that since 1.10.0 release the generated release tarball includes the generated manpages too; in which case neither the use of a2x nor --disable-manpage-support is required.
