[PATCH] libgloss/arm: Add linux syscall interface.

[Shaun Jackman]

I regret my delayed reply; I broke my wrist a couple weeks ago, and
the injury makes typing laborious. With luck, I should be healed up in
another week.

The primary purpose of this work is a robust system call layer. I
expect to add functions in C source form to linux-syscalls1.c only
when necessary to shim between the user-space section 2 function and
the system call, such as wait and waitpid calling wait4.

I do hope there would be low resistance to any requests of the form
`if we only add syscall X to linux-syscalls0.S we can run application
K'. Through this method I've been able to to port busybox to arm-elf
-- initially using libgloss-rdp, then briefly libgloss-redboot, and
now finally libgloss-linux.

It's certainly a task I'd be interested in. It's just a matter of
finding the time.
