OK, I got gcc-4.8.2 to compile.
I installed it in a mock chroot and "fixed" FF to not use the bundeled gcc.
the FF build now fails on me with these errors:

make[5]: *** [Unified_cpp_js_src3.o] Error 1
</error_msg>
I wonder how this can fail while the same code compiles on RSEL7 :(
google does not hold any answers today.
Probably the best course of action is to review all patches included in
FF for 6.7 vs those in 7.1 and see if something points in the direction
of these errors.
but first I'm going to test TB.
