Comment(by erikd):

 It seems like the logic which sets USE_MMAP:

 {{{
 #if defined(linux_HOST_OS    ) || defined(freebsd_HOST_OS) || \
     defined(dragonfly_HOST_OS) || defined(netbsd_HOST_OS ) || \
     defined(openbsd_HOST_OS  ) || \
     ( defined(darwin_HOST_OS ) && !defined(powerpc_HOST_ARCH) ) || \
     defined(kfreebsdgnu_HOST_OS) \
 }}}

 should be changed to:

 {{{
 #if !defined(powerpc_HOST_ARCH) && \
     (   defined(linux_HOST_OS    ) || defined(freebsd_HOST_OS) || \
         defined(dragonfly_HOST_OS) || defined(netbsd_HOST_OS ) || \
         defined(openbsd_HOST_OS  ) || defined(darwin_HOST_OS ) || \
         defined(kfreebsdgnu_HOST_OS) ) \
 }}}

 so that powerpc_HOST_ARCH is tested regardless of the OS.
