That shouldn't bee too difficult.

As a hint, make adds 's' to the environment variable MAKEFLAGS:
MAKEFLAGS=s

MFLAGS=-s also exists, but its use seems to be superceded by MAKEFLAGS

When I change ltmain.sh using the following patch, it seems to work. I am 
using
# libtool --version
ltmain.sh (GNU libtool) 1.5.22 (1.1220.2.365 2005/12/18 22:14:06)

I hope this patch is portable.... I am certainly no expert in portability!
