[Buildroot] GCC - march=geode doesn't exist?

[Buildroot] GCC - march=geode doesn't exist?

[William Pettersson]

Ok, so I'm still working on this Soekris, using gcc-4.2.0.  4.2.0
doesn't support -march=geode or -mtune=geode, but BR2_GCC_TARGET_ARCH
and BR2_GCC_TARGET_TUNE are both set to "geode" if you select the geode.
 Now apparently gcc-4.3.0 has plans for a geode target, but as 4.3.0
isn't stable yet, I've attached a patch which makes the "geode" select
"i586" for BR2_GCC_TARGET_TUNE and BR2_GCC_TARGET_ARCH.

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..

TIA,
