[armedslack] Changing initrd installer to use uClibc

[Stuart Winter]

Hi

Because the initrd uncompressed is about 18MB now - I am thinking
about rebuilding it using uClibc.  It's easier said than done --
there looks to be a lot of initial development work required, and
I'm not yet sure of the payoff. The idea would be to reduce the
amount of RAM required to run the installer.
My current thoughts are that you need more RAM to run the installer
than you do to run a basic installation of ARMedslack.

Reducing the amount of RAM required would help making the installer usable
on portable non-desktop ARM devices too, I suspect.

I might download one of the pre-built build roots and
build some stuff, and if it works out, build my own build-root.
Any thoughts?
