Re: sparc: ld: --relax and -r may not be used together

[Riccardo Mottola]

Hi Nicola,


I forgot to mention that I commited the patch, but then today I read 
your message later about gcc 4.6. Since the majority of people use x86 
it is perhaps better to back it up? Or else, find a way for configure to 
detect and handle this.

Thanks,

Riccardo
