That's a slightly different problem: -Wl is a gcc flag that means
"pass the following flag through to the linker".  Since AC_LINK_IFLESE
uses $CC and not $LD, this works in configure, but apparently bare ld
does not understand -Wl.  The only way I can think of right now to fix
that is to manually invoke $LD inside the test macro.  Lemme have a
bit more of a think.

usually comes from bad judgement.
