Something like that.

Well, to be fair, the current rule should be right, or close to it,
for most ELF systems, not just Linux.

Actually, another issue with this is that currently we build all the
libfdt objects with -fPIC, which significantly increases their size.
That tends to frighten people who are looking at building libfdt into
their firmware.
