I think I'm wrong.  At least, I've managed to confuse myself.

The if-cross-compiling branch of configure.in states "hard code the things
which would require linking," but then calls CHECK_LINKER_FEATURES anyhow.
CHECK_COMPILER_FEATURES only tries to compile something, not link, but
it's commented out, and its guts are hardcoded instead.

This seems backwards to me; surely we can CHECK_COMPILER_FEATURES without
needing a linker, and only CHECK_LINKER_FEATURES needs to be avoided?
