Disable --whole-archive when using convenience archives

[Alon Bar-Lev]

Hello,

Using:
autoconf-2.63
automake-1.10.2
libtool-2.2.6a

I have some convenience archives linked against several modules.

I wish only required objects to be included in modules.

But libtool's usage of --whole-archive forces the whole archive to be included in the module.

I could not find any way to disable the --whole-archive injection.

In the following example, both a.c and b.c are compiled and added to module.so, although
only a.c is actually used.

Removing the -Wl,--whole-archive from compilation solves this issue.

The following is produced by libtool:

bin/sh ./libtool --tag=CC   --mode=link gcc  -g -O2 -avoid-version -module -shared -no-undefined   -o module.la -rpath /usr/local/lib m.lo lib1.la
libtool: link: gcc -shared  .libs/m.o  -Wl,--whole-archive ./.libs/lib1.a -Wl,--no-whole-archive     -Wl,-soname -Wl,module.so -o .libs/module.so

Can anyone help?

Thanks!
Alon Bar-Lev.
