Package request: dosemu

[SDRausty]

DOSEMU stands for DOS Emulation, and allows you to run DOS and many DOS programs, including many DPMI applications such as DOOM and Windows 3.1, under Linux.

DOSEmu can run only on x86. See this: https://wiki.debian.org/Arm64PortANFUList

No problem here, dosemu package should be totally possible.

Just because package isn't available on arm doesn't mean we shouldn't NOT support it, since there are plenty of environments in which Termux is indeed running on x86 hardware.

To run a DOS emulator we need graphical output in Termux. @vishalbiswas has added a repository with X11 packages, so we can access graphical output with VNC (but third party VNC viewer is required).
Now X components are available here: https://github.com/xeffyr/termux-x-repository

@SDRausty, yes DOS is not GUI. But dosbox requires SDL.

Dosbox is available in x11-packages repository.

pkg install x11-repo
pkg install dosbox

But note that this will require a little more setup than just installing package.

Not only it is unavailable for ARM, a Portage ebuild file says

dosemu does not work on clang due to missing 16-bit assembly support: https://bugs.gentoo.org/729240. Please try gcc.

Probably we may package it only for x86 and amd64, and allow installing it to some custom prefix for aarch64 for running it with qemu/fex/box64.

Well, I think the new dosemu (dosemu2) have emulator already. However I don't think we need it, because DosBox also emulate x86 CPU.

However dosemu2 is on TUR repository in PR, but must be cleaned
