Yes, somebody already mentioned about the same for itanium. I added
those bits with just a copy of gcc-trunk at hand..
Can you check your manpage of gcc-4.2 to see what itanium variants are
supported there and fix those and geode according to:
default foo if BR2_foo && BR2_GCC_VERSION_4_3
default bar if BR2_foo && !BR2_GCC_VERSION_4_3
default baz1 if BR2_baz && (BR2_GCC_VERSION_3_4 || 4_0 || 4_1)
etc..
