Multi lib 32 bits support

[address@hidden]

Hello:

The new released libtool 2.4 fixed my compilation problem while linking 
a dll with code compiled with -flto.
Now I have new problem with 32-bit.

I think libtool 2.4 breaks multi-lib 32-bit.
For 64-bit it was ok.
Also I didn't notice this error while using older libtool came with the o/s.
ltmain.sh (GNU libtool) 2.2.6b

At link time it used gcc to link a *.c object file but failed to pick 
the right path to the correct library.

It picked up lib/gcc/x86_64-w64-mingw32/4.5.2/libstdc++.a
instead of picking up lib/gcc/x86_64-w64-mingw32/4.5.2/32/libstdc++.a

Is this a know issue?

Regards.
