With glibc 2.21 (Debian/unstable on x86_64), on any code compiled by

this is a bug in tcc or in the glibc.
According to Aurelien Jarno, this is actually due to new binutils
relocations (and the Debian glibc 2.21-4 package is built with a recent
binutils, hence the problem with it).

Blaeh. I didn't consider the case of the libc runtime startup .o files
when agreeing to the new relocs. Arguably those object files exposed to
every linker trying to create user-space programs shouldn't use the new
relocs (they provide a very minor performance benefit sometimes) even
with new binutils (and so that's a QoI issue in glibc), but it's easy
enough to deal with them in tcc.
Try newest mob again.
Ciao,
Michael.
