Makefile: Fix Windows build

Now using sdl2-config to generate correct cflags and ldflags in
Makefile.

Tested working on Windows 10 in MinGW-64 and command prompt (cmd).
There are some wierd issues however, in cmd, minigbs goes into
background and can only be quit using task manager. Additionally, text
is not displayed when using MinGW-64 until minigbs is quitting.

This commit will be tagged a release to provide a statically built
executable.

More tweaks to new -dd debug mode.

New test ALSA impl w/poll. Add goto key + conffile

Goto track key is return/enter.
Config file currently only used to persist the volume.
  It's located at $XDG_CONFIG_HOME/minigbsrc
  (or ~/.config/minigbsrc if XDG_CONFIG_HOME is unset).

Wave channel improvement + note display fix.

Wave channel wasn't always setting the sample properly, it should now be
less whiny. Kirby's dream land track 1 is a good test.

Fixed note display sticking if the track used a 0 volume write
(DAC disable) to cut notes. (e.g. Ottifanten Kommando Stőrtebeker)

Quick fix for noise channel divide-by-zero

add support for files using tma/tac timing
