Changeset 6a8700d in rtems for c/src/lib/libc/error.h

Patch from Ralf Corsepius <corsepiu@…> to:

This is the diff to let gcc-target-default.cfg use LINK.c -Wl,-r
instead of LD -r for building *.rels.

BTW: gcc -r works but seems to be undocumented, however

as gcc -r -v shows it seems to works. Now I am using -Wl,-r :-)
