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.
