You should use AC_TRY_LINK or something similar to check for toolchain support. Hardcoding a given set of strings matching the version is generally not a good way of writing a check; if you check something, check it for real. Also if you pass -Wl,--as-needed to the compiler that's what you should check rather than if the supposed linker supports --as-needed; I suppose AC_TRY_LINK will do that. A.
