Re: [Xen-devel] problems compiling xen on a crusoe

[A Streetcar Named <desire@xxxxxxxxx>]

-nopie fixed the  originally reported error, but I subsequently got
other errors that said something like "undefined reference to
`__guard'" and "undefined reference to `__stack_smash_handler'". 
Adding -fno-stack-protector seems to have solved these as well, and
I'm now compiling the kernels for the crusoe.

Thanks!
