Ah, yes. The original linker script put the .fpc stuff inside .data, and 
then .threadvar right after it. To keep the same layout, I added the 
explicit placement for .threadvar. Then ld told me I couldn't insert 
".data after .data" in my augmentation script, so I changed it to 
.fpcdata, which in then caused the overlap (with ".data after .data", I 
thought it would just put it at the end of the .data).

Perfect, now everything works!

Thanks again.
