LM32 4.6 toolchain

[Sebastien Bourdeauducq]

Hi,

to my knowledge, the LM32 GCC build failure in 4.6 is only related to
the C++ compiler, which was broken anyway (generating incorrect code) in
4.5.x. Can we simply disable it and upgrade the toolchain RPMs to 4.6
with the C compiler alone?

Thanks
Sébastien
