[Buildroot] Problems with some x86-Target Architecture Variants

[Simon Pasch]

There are missing some x86-architecture-variants in Config.in. Without
them it isn't possible to build the toolchain with build-optimization.

Perhaps someone could look over the instruction-set versions...I tried
my best to find the correct ones.

geode is i586

gcc-4.3 supports these:
generic
native
i386
i486
i586, pentium
pentium-mmx
pentiumpro
i686
pentium2
pentium3, pentium3m
pentium-m
pentium4, pentium4m
prescott
nocona
core2
k6
k6-2, k6-3
athlon, athlon-tbird
athlon-4, athlon-xp, athlon-mp
k8, opteron, athlon64, athlon-fx
k8-sse3, opteron-sse3, athlon64-sse3
amdfam10, barcelona
winchip-c6
winchip2
c3
c3-2
geode


See the archives for a suggestion on how to please older versions of gcc
http://www.nabble.com/GCC---march%3Dgeode-doesn't-exist--t4108131.html
(or set your BR2_EXTRA_GCC_CONFIG_OPTIONS, BR2_TARGET_OPTIMIZATION
accordingly).

The hunk below is not really appropriate.
