Subject: help with lorder and tsort not giving proper output...

well.. after looking at the source to tsort it looks like tsort imports
the dependances backwards... either that... or when making libs another
program is needed to reverse the output of tsort...  I have a fix at the
end of this message..  if you want me to submit a pr I will...

output from lorder:
fdprintf.o fdprintf.o
genconvert.o genconvert.o
linklist.o linklist.o
genconvert.o linklist.o

as you can see genconvert.o depends on linklist.o... but when you run this
output through tsort you get:
genconvert.o
fdprintf.o
linklist.o
