What do you want the buildd maintainers to do? If you suspect that a
rebuild will fix the issue, we can trigger a binNMU and see whether it
does; otherwise, please direct porting questions to the debian-powerpc
mailinglist only.
(it might be nice to analyze a backtrace of a segfault to figure out
where the crash comes from, though)

"The buildd is broken" would mean something like "the buildd has a
corrupt /var/lib/dpkg/status file" or "the compiler was incorrectly
installed on the machine", or something similar. If the compiler is
installed correctly but generates broken code, that would mean a bug in
the compiler. This I find extremely unlikely, however; it's much more
likely that the bug is in apt, but that it is a porting issue that is
powerpc specific.
If that is the case, there are two things you should look at:
- endianness: i386 is little endian, powerpc is big endian. If your code
makes assumptions about endianness in some places, verify that code.
- assumption about char signedness: 'char' is unsigned on powerpc, and
signed almost everywhere else. If you have a 'char' datatype
somewhere, verify whether the code tries to assign a negative value to
that variable; if it does, then that's probably your bug and you
should either change the code to not make assumptions, or change the
declaration to say 'signed char'.
