The ppc1 you see in the make output uses the RTL of its own revision
compiled by your previous 2.7.1 compiler. Now some change inside the RTL
and maybe the compiler results in your previous compiler to generate a non
The problems that occur when you use an older dev version to compile a
younger one can sometimes be very strange. I often had the problem myself
when I forgot to switch back from the trunk compiler to the last release

and as far as I've understood the softfloat discussion it should also work
on hardfloat systems. Otherwise you could compile a hardfloat compiler on a

I should rename my ubuntu to something else because it is no longer a true
ubuntu since it is very similar to mint. I took out unity and its companion

You should be able to take your 2.6.2 hardfloat ppcarm binary only from
your Ubuntu and copy that to your funtoo. You can then invoke the
compilation this way:
make clean all FPC=/path/to/2.6.2/ppcarm
You should nevertheless have your 2.7.1 bin directory in $PATH as a few
other tools (e.g. data2inc) might be needed when installing (don't know
whether we changed that already to use the freshly compiled one first...)
