Bisecting lead me to this change which is probably just hiding the real
problem:

(sid_powerpc-dchroot)glaubitz@perotto:~/guile-git$ git bisect good
a68c80c747a2a8ec92fa84684ebd60b4ecb7ffa0 is the first bad commit

    Switch to baseline compiler for bootstrap/

    * bootstrap/Makefile.am (GUILE_OPTIMIZATIONS): Add -Ono-cps so that we
      use the baseline compiler when bootstrapping.

I'll try to bisect again with "-Ono-cps" removed after it is introduced.

FWIW, there is a big-endian PowerPC machine available in the gcc compile
farm if anyone wants to help track down this issue [1].
