Re: [Ltib] Linking question

Hi Luka,

No, the toolchain is not rebuild.  Those options are injected to the 
selected cross toolchain.  Within a package build (rpm spec file) gcc is 
an alias for a toolchain wrapper, the wrapper will pick up and inject 
any flags you've set in the config.

Regards, Stuart
