since I am the one who does not want to relicense the ARM32 backend, I give
you and everyone else permission to use my ARM backend code as a template
for a backend for another instruction set as long as you release it as open
source software under the license found in the RELICENSING file in TinyCC
(or the LGPL). To me ARM Thumb is a different instruction set.

My intention is not to hinder development of TinyCC. What I want to prevent
is that TinyCC gets hidden in closed source products. The LGPL does allow
commercial use. People just have to read and follow the license.
