There are about 9k worth of GOT. In which way does it overflow?

Well, it doesn't. I saw a bunch of errors:

(.text+0x12c1e): relocation truncated to fit: R_68K_GOT16 against symbol `_GLOBAL_OFFSET_TABLE_' defined in .got.plt section in /scratch/maxim/cf-fsf/obj-linux/glibc-mainline-0-m68k-linux-gnu-i686-pc-linux-gnu/default/csu/abi-note.o

and remembered about this default in binutils. Upon closer inspection I noticed that the relocations are R_68K_GOT16, not R_68K_GOT16O, so something else should've broken.

Still, I think it's time to enable multiple GOTs by default for m68k-linux.

Thanks,
