David Herrmann b8ffc23875 build: check for build/link flags harder ... Use AC_LINK_IFELSE instead of AC_COMPILE_IFELSE to test for flags that might succeed during compilation but not during linking. An example is gcc compiled with libssp support but gnu-ld without it. In this case -fstack-protector works fine during compilation but fails during linking as several internal helpers are missing.
