There is a new pull request by gco against master on the mblaze repository

https://github.com/gco/mblaze stackprot
https://github.com/leahneukirchen/mblaze/pull/229

use -fstack-protector-strong for both compiling and linking
gcc needs -fstack-protector-strong when linking else `__stack_chk_fail` and `__stack_chk_guard` are not defined (at least on Solaris).

A patch file from https://github.com/leahneukirchen/mblaze/pull/229.patch is attached
