Comment 4 for bug 318304

Here's some explanation:

> - ARCHOPTS=-march=pentium-mmx \
> + ARCHOPTS=-march=pentium2 \
sdlmame requires fast machines or it runs so slow it's unusable; optimization for i686 offers some performance improvement (comment put in changelog)

> -Standards-Version: 3.7.3
> +Standards-Version: 3.8.0
prevents lintian from complaining with the following warning:
W: sdlmame source: out-of-date-standards-version 3.7.3 (current is 3.8.0)

> -Architecture: i386 amd64 lpia powerpc
> +Architecture: i386 amd64 powerpc
lpia architecture is not supported upstream (comment put in changelog)

configuration file "joymap.dat" removed upstream, above are related changes:
manpage: documented new command option; removed reference to joymap.dat
mame.ini: removed reference to joymap.dat
sdlmame.conffiles: removed reference to joymap.dat
(already documented in changelog)

Thank you!
