The base library configuration for the CodeSourcery x86 toolchain is
Intel Pentium 4. I am not sure the VIA C3 implements the Pentium 4
instruction set, I am not very familiar with those x86 clones.

Hum, this is interesting. Maybe when it's statically linked you don't
hit the problematic code paths?
Can you paste the complete panic message, so we can have a look?

Probably nothing is wrong with the VIA board, most likely with the
toolchain configuration.
Can you try BR2_x86_c3=y, dynamic linking, with the Buildroot internal
toolchain?
Thanks,
Thomas
