Ah sorry! I can explain more. I was wondering if there were plans to
support building toolchains with the LSB-sdk.
http://linuxtesting.org/lsb_sdk
Basically, the sdk will help compile the toolchain to follow the LSB
standard. This means the resulting toolchain will be more portable
between different linux systems.
https://wiki.linuxfoundation.org/lsb/start
We will need to download the sdk, setup the environment, then change a
few configure options here and there.

The installation directory.

Sounds good to me. I still need to work out the details myself, but if
it sounds reasonable... Sure! I can do a small write-up first.
