This is another one that the gcc build system **could** build for you.
Again, going to just install a copy of the current release for the compiler building to come.

Ah, that one went relatively smoothly:

Spoiler:

The content of my pset.sh file:

export PATH=/opt/qemu111/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

From the location of the AL install:

core2quad system-image-armv6l $ . pset.sh
core2quad system-image-armv6l $ ./dev-environment.sh

  Type exit when done.

(Whoot!  That worked, even with the libtoolized build!)

(Our release tar-ball:)

(Install it for ourselves:)

(Ease on out of the emulator:)

(armv6l:1) /root # umount /home
(armv6l:1) /root # exit
Restarting system.

And the only things lost along the way so far was 'long double' and 'decimal float'.

This is another one that you install by 'dumping' it on the emulator's /home directory.
