Thank you Edmund, but it does not work (see below).
Btw, do you know that can ask for an account on GCC Compile Farm Project (see: https://gcc.gnu.org/wiki/CompileFarm) Here you can have remote access on different machines for free.

I'll push this in about 24 hours if nobody objects. TCC might work on the "APM X-Gene Mustang board / Ubuntu 14.04.3 LTS" with this. Use R_AARCH64_MOVW_UABS_G* instead of R_AARCH64_CALL26.
