   I gave it a full test with PowerPC GNU/Linux and sniff test with 
   powerpc-elf.  If there are other problems, I'm sure they'll be sorted out.

Really?

fork-child.c:fork_inferior()

solib.c:solib_create_inferior_hook()

TARGET_SO_SOLIB_CREATE_INFERIOR_HOOK

current_target_so_ops->solib_create_inferior_hook()

which, if you don't include any of:

   solib-aix5.c
   solib-frv.c
   solib-irix.c
   solib-osf.c
   solib-sunos.c
   solib-svr4.c

is a null pointer.
