Just use the Linaro 14.09 toolchain that is pre-defined in Buildroot.
Buildroot will automatically download it, extract it and set it up for
you. I.e nothing to do or worry about.

Which HW platform are you working with? We already have some packages
for the Mali GPU drivers for some platforms. And we could add more.

Basically, it seems to me that you are trying to hack very complicated
things while there are much simpler and better solutions that exist and
that you don't know about.
