[yocto] How to disable SIMD extensions (mmx, sse3, ...)?

[Mauro Ziliani]

Hi all.

I'm working with a Geode LX800, porting an old application Debian-based 
into Yocto Thud.

I need to disable some multimedia SIMD extensions for gcc compiler.

Where I can do this?

I suppose I have to disable SIMD extensions in 
conf/machine/geode_lx800.conf file (the machine descriptor file), but I 
cannot find any document about.


Can you help me?
