Bernd Schmidt writes:
This introduces a new SEND_EARLY_STDERR macro that is to be used in dl-startup.c before ld.so is relocated. It is needed on Blackfin (and frv) FDPIC since we have to use special tricks to get the address of a string constant. EARLY_STDERR_SPECIAL gets defined on such a machine and prevents printing of debug strings inside the loop that relocates ld.so, since we can't decide which of the two variants to use.
