The build environment is older than aboriginal.
It is this one
http://uclibc.org/downloads/binaries/0.9.30.1/mini-native-x86_64.tar.bz2
So I guess its a bit long in the tooth.
I dont want you guys to spend your valuable time chasing bugs if its just
me that sees them.
Regarding the bash version, I use the above environment, but slightly
upgraded (bash, tar).
I set REALGCC to rawgcc, and I also needed to change the musl gcc.spec
file, to find all object files, patch I use below (linewrap damaged):
bash-4.1# more all/musl-0.9.6-1/musl-gcc.specs.pat
