Log message:
Rename old-mame-license to mame-license, because I found an older MAME
license.

mame-license is the last license used by MAME prior to their switch to
"modified-bsd AND gnu-gpl-v2".

Log message:
Rename picodrive-license to old-mame-license, reflecting its origin.

Some packages which are neither old versions of MAME or Picodrive
use this license in wip, and will be imported soon(TM).

Log message:
emulators/libretro-picodrive: add a patch to stop the makefile overriding CC.

Log message:
emulators/libretro-picodrive: Explain why someone might want to use this
in the DESCR.

Log message:
emulators/libretro-picodrive: Update to 20180722.

According to picodrive's author, the code is unsuitable for big endian
platforms. Libretro doesn't provide Picodrive binaries for any of their
supported big endian platforms (mostly PowerPC games consoles). Instead,
they provide Genesis Plus GX, which I shall add to pkgsrc soon(TM).

For now, disable building libretro-picodrive on big endian.

No upstream changelog, unfortunately.

Import libretro-picodrive-20150203 as emulators/libretro-picodrive.

Libretro is a simple but powerful development interface that allows for the
easy creation of emulators, games and multimedia applications that can plug
straight into any libretro-compatible frontend. This development interface is
open to others so that they can run these pluggable emulator and game cores
also in their own programs or devices.

PicoDrive is a Sega 8/16 bit video game system emulator.
