That didn't help. In fact, cc-option is undefined, so it did nothing. I tried correcting this to check_gcc:
--- linux-2.6.8/arch/ppc64/Makefile.old 2004-09-20 07:04:35.000000000 -0700 +++ linux-2.6.8/arch/ppc64/Makefile 2004-09-20 07:06:38.000000000 -0700 @@ -28,6 +28,7 @@ LDFLAGS_vmlinux := -Bstatic -e $(KERNELLOAD) -Ttext $(KERNELLOAD) CFLAGS += -msoft-float -pipe -Wno-uninitialized -mminimal-toc \ -mtraceback=none +CFLAGS += $(call check_gcc,-mcall-aixdesc)
This actually affected the build in that -mcall-aixdesc was used on many compiles, but the build still ended with the same errors:

Got another suggestion? Thanks, Dan
