Add bc dependency

Screenfetch doesn't work properly unless we install our version of bc.

If readline is installed from Chromebrew the stock version of bc starts
throwing errors related to libreadline.

Disable MPI assembler modules for ARMv8

The included MPI assembler code doesn't work for the ARMv8 processor in
the Samsung Chromebook Plus (and possibly others). Until upstream adds
support for these processors they must be disabled for the package to
build properly.

In the future support will probably be added for these processors
enabling us to re-enable support for MPI ASM modules.

Adding tree dependency to pass

The pass program requires tree to list the stored passwords correctly.

Add XWayland

Add clozure common lisp package

Adding elinks package

Clozure CL (often called CCL for short) is a free Common Lisp implementation
with a long history. Some distinguishing features of the implementation include
fast compilation speed, native threads, a precise, generational, compacting
garbage collector, and a convenient foreign-function interface.

Intel machines have both 32-bit and 64-bit versions available. ARM machines
currently only have a 32-bit version available. 64-bit for ARM is in
development.

This is more likely to stay up longer than my personal Gogs mirror.

Add Micro editor package

[compressdoc] Download single file instead of archive

We only require the shellscript named compressdoc but have been
downloading a 1.9M archive and then copying the file into our bin
directory.

This changes the behavior to download the one file that we need via
Github's raw user content service.

It also simplifies the installation to a single line using the install
command.

Add owl package
