From Robert Boehne:

Yes thank you for this workaround but ld didn't like it:
/usr/bin/ld: unrecognized option 
'-L/usr/lib/gcc-lib/i586-mandrake-linux-gnu/2.96/../../..'
/usr/bin/ld: use the --help option for usage information
collect2: ld returned 1 exit status
Without quote, expression links good so ...

1/ I think there isn't any options in automake / libtool for do what I want.
2/ -whole-archive flag is os dependant, and already defined in libtool, 
I must use it
3/ I must do an automake / libtool patch that:

  a/ In automake, define something in automake template, something like
  mybinaries_WHOLE_LIB = myfirstlib.la mysecondlib.la
  This variable isn't in use without --disable-shared flag

  b/ If --disable-shared option of configure is in use, automake must
  remove libs that is two times on link command and keep only this with
  whole-archive flag.

  c/ Add a -whole-archive options in libtool that use os specific option
  for link a library into a binarie

What you think of this ?
