Does anyone have any hints on what could be going on?


If you're expecting to get powerpc64 support with powerpc-*-rtems*,
then you will need to add --enable-64-bit-bfd on a 32-bit host.

config.bfd has targ64_selvecs="powerpc_elf64_vec powerpc_elf64_le_vec"
for powerpc-*-rtems*, and if you trace how targ64_selvecs gets to be
added to targ_selvecs you'll see you need either host64 or want64
true.


Thanks! It never occurred to me that I was on a 32-bit host.

I will try to fix this in the recipes in the RTEMS Source Builder
tomorrow.
