+Makefile.in: Use LIBS from configure rather than specifying -lfcgi manually.
+
+libfcgi needs libm and fcgiwrap does not use libtool or pkgconf to
+detect libfcgi, so we need to add -lm explicitely when using static
+libs.  Buildroot does this by providing LIBS=-lm to configure when
+needed.  However fcgiwrap does not use Automake and its Makefile.in
+ignores LIBS from configure.  Fix it with this patch.
