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.
Wouldn't it make sense to enable this option by default if you build cross
No, if you are hosting on a 32-bit machine for a 32-bit target, why
should you pay the penalty of calculating addresses, relocs etc. using
64-bit arithmetic? Your compiler might not even support long long, or
if it does, the support might have bugs.
For native tools I completely agree with this point of view, but for
cross tools I think the situation is different. If you have a broken
compiler, then you can still use --disable-64-bit-bfd.
