Only put flags in LDFLAGS. Put libs in LDLIBS. The default rule is

and LINK.c embeds LDFLAGS. On ELF platforms where command-line order of
linker inputs doesn't matter so much, it'll often work to put -l options in
LDFLAGS, but it's not portable to PE platforms like Windows/Cygwin where the
libraries have to come last on the command-line.
