Re: undefined reference to `__stack_chk_guard' with sparc crosscompiler

[Adhemerval Zanella <adhemerval dot zanella at linaro dot org>]

I hit this same issue and fixed by adding 'libc_cv_ssp=no libc_cv_ssp_strong=no' 
while configuring GLIBC. I know the idea is not rely on such options, but
I did not want to waste time understanding the problem with my sparc bootstrap
compiler config.
