Just to report that since this change, my tinderbox is somehow ending up with
'auto' inside my Libs.private in fontconfig.pc, e.g.

Libs.private:  -lexpat -lfreetype -lz -lbz2   auto

which causes things which depend on fontconfig to fail to build with "gcc:
auto: No such file or directory", e.g [1]

Cygwin uses a separate libiconv, but it looks like this isn't handled
correctly anymore.

Should this comment read "if any of" ?

I think libiconv_lib can have the value "auto" here, which leads to the
AC_TRY_LINK test failing, even though it shouldn't
