Specs can't be trusted, sadly.

Look for dbase in gcc/unwind-dw2-fde-glibc.c to see the initialisation for
datarel base, used by x86 and frv.  Look for ia64 in gcc/unwind-generic.h to
see how ia64 sets up datarel base.  A datarel value is relative to this base
address.  Except to muddy the waters further, DW_EH_PE_datarel when used in
.eh_frame_hdr takes its base to be the address of the .eh_frame_hdr section!
