Hi, thanks for this patch!  But I'd like to solve the problem in a
slightly different way.  gdbserver is a sort of proxy for GDB, in that
uses the same process control bits (ptrace, /proc, etc) as does native
GDB, but stripped down to fit in the small dedicated program.  However,
in the long run it's a weak strategy to maintain a pseudo-clone of
native debug support; instead I think we should work up a way to allow
gdbserver and gdb to share the low-level bits and thus automatically
have gdbserver for every port.

We can take a step along this path by making a separate low-armlinux.c
for ARM Linux and so forth, and then making low-linux.c generic.  If
you do the ARM Linux bits, I'll help with making the other changes.
