compile fails on ppc 10.4.8

[russt]

autoconf succeeded on os 10.5.8 ppc with gcc 4.0.1 (g4).

compile succeeded, but failed in link for jamvm:
"_Gestalt", referenced from:
_getPhysicalMemory in libcore.a(os.o)
"_jni_stubs", referenced from:
_jni_stubs$non_lazy_ptr in libcore.a(dll.o)
"_jni_static_stubs", referenced from:
_jni_static_stubs$non_lazy_ptr in libcore.a(dll.o)
"_convertSig2Simple", referenced from:
_setJNIMethod in libcore.a(dll.o)

The _Gestalt can be patched by linking against -framework CoreServices, which looks like it is present in LDFLAG in the generated makefiles but is not making it into the link step.

Not sure about the other missing symbols, I think they should be coming from the local build. I don't see any other errors in the output.
