configure: Check for actual functions in libraries with AC_CHECK_LIB
Checking for `main` produces code like this in the test program:
int
main ()
{
return main ();
;
return 0;
}
This recursive call results in a warning message with some compilers (e.g.
Clang in newer Xcode versions: "all paths through this function will call
itself [-Winfinite-recursion]"), which lets the tests fail when compiling
with -Werror.
