unable to build universal for ppc64

[Roger Pack]

Hello, I noticed today when trying to rebuild all my ports as
"universal" that the first time it hit a "from source" compile
requiring package (in this case, gmake), config.log showed this:

configure:3186: checking whether the C compiler works
configure:3208: /usr/bin/gcc-4.2 -pipe -O2 -arch ppc -arch ppc64 -arch
x86_64 -arch i386 -I/opt/rdp_project_local/include
-L/opt/rdp_project_local/lib -arch ppc -arch ppc64 -arch x86_64 -arch
i386 conftest.c  >&5
ld: warning: in /usr/lib/crt1.10.5.o, missing required architecture
ppc64 in file
ld: warning: in /usr/lib/libSystemStubs.a, missing required
architecture ppc64 in file
ld: warning: in /usr/lib/libSystem.dylib, missing required
architecture ppc64 in file
ld: could not find entry point "start" (perhaps missing crt1.o) for
architecture ppc64
collect2: ld returned 1 exit status
lipo: can't open input file: /var/tmp//ccHqUCE5.out (No such file or directory)
configure:3212: $? = 1
configure:3250: result: no

I assume this is expected somehow?
Thanks for your feedback.
