Yes it works

I included the line 

_LT_AC_TAGVAR(archive_cmds_need_lc, $1)=no

Both under 
case $CXX


case $CC

leaving the following piece as it is
> # Assume -lc should be added
>  _LT_AC_TAGVAR(archive_cmds_need_lc, $1)=yes

make was errorless and so was the libtool usage with my programs!!

It's not the right patch. The problem is that people keep changing the way 
archive_cmds_need_lc is calculated and overrides whatever I set it to (it is 
set to no in the beginning as default). Sometimes it works in libtool HEAD 
sometimes it doesnt. I would rather remove this part:

> # Assume -lc should be added
>  _LT_AC_TAGVAR(archive_cmds_need_lc, $1)=yes

Since it is obviously wrong and breaks linking on some platforms.

Another way to protect us from random breakage in libtool, could be to 
introduce an extra variable "archive_breaks_with_lc" that overrides need_lc 
if set to yes.
