| Subject: [PATCH] configure.ac: fix build without stack-protector |
| |
| Compiler based hardening (including -fstack-protector-strong) are |
| enabled since version 3.0.3 and |
| https://github.com/lxc/lxc/commit/2268c27754152aa538db2c9e3753d72d19bcd17a |
| |
| However, some compilers could missed the needed library (-lssp or |
| -lssp_nonshared) at linking step so use ax_check_link_flag instead of |
| ax_check_compile_flag |
| |
| Fixes: |
| - http://autobuild.buildroot.org/results/0b90e7dca2984652842832a41abad93ac49a9b86 |
