Remove support for the Sun386i. (#329)

Browse Source 
This was a machine running SunOS 4, which we no longer support.

It had an odd display controller and a compiler with issues that
required workarounds. Those compiler issues aren't an issue in
today's world, so we don't need to keep the workarounds present
for reference.

It had a bit of inline assembly, but that is still present in
other files for other platforms.
