| Subject: [PATCH] configure.ac: use CC instead of gcc, full link for stack |
| protector test |
| |
| Using gcc directly is incorrect when cross-compiling, $CC should be |
| used instead. |
| |
| Also, for the stack protector test, a full link is needed, since just |
| the compilation can work, but the link can fail due to libssp not |
| being available in the toolchain. |
