Try using i686 instead.

You have CMOV and MMX, as well as 3DNow! instructions -- with
extensions. That makes it an Athlon "lite" processor, or a K6-3 with
CMOV instructions. These are enough to make it compatible with the
Pentium Pro (i686) architecture, and a bit more besides.
Here are my flags from the box on which I am composing this message, a
dyadic Athlon MP (Barton core) system:
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 mmx fxsr sse syscall mp mmxext 3dnowext 3dnow
[Both CPUs reported the same CPUID flags.]
I guess the Geode is quite "lite" compared to a late-model Athlon.
To the O.P.: your CHOST should be 'i586-pc-linux-gnu' to support all
the processors you have listed, and -march=i586 will allow you to
compile once for all your processors.
