your goal will be reached by using switch -all-static instead of 
-static, because -static is now caught by libtool and has a different 
meaning.

-static means all libtool libraries will be linked statically
(only if possible... if a used libtool library doesn't exist in static 
version, the build process falls back to link the respective library in 
shared version)
 
-all-static instead forces the build process to link all libraries 
statically
(if a used library doesn't exist in static version the build process 
fails or hangs *sigh*)

BTW:
Calling "libtool -help" and/or "libtool -help -mode=link" shows you the 
features of your libtool script.

Answering point 4):
that's right, libtool script is used... why not?

Libtool is a shell to cover compiler/linker calls to handle (almost) all 
situations of project's build and run and debug process, which use 
project-libs and/or published libs.
