On BSD make, $> is an alias for $^. On both GNU and BSD make, $^
is supported. Specifying both resulted in duplicate object files
passed to the linker:
ld: error: duplicate symbol: main
>>> defined at tinywl.c:887
>>> tinywl.o:(main)
>>> defined at tinywl.c:887
>>> tinywl.o:(.text+0x0)
cc: error: linker command failed with exit code 1 (use -v to see invocation)
Only use $^ and remove $>.
