This problem is still around after Juan's Makefile reorganizations.

Before, I had provided two alternative patches:

* The first version wrote the list of libqemu_common.a's and $ 
(HWLIB)'s object files into a text file from Makefile[.hw] that was  
later read in Makefile.target.

* The second version was using dedicated Makefile[.hw] targets for  
printing the object files to stdout for use by Makefile.target,  
avoiding the need to write an intermediate file.

Avi had preferred a variation of the first version for reduced  
complexity.

Other ideas that crossed my mind were:
* using GNU ld directly instead of gcc for linking (broken by -Wl and  
some other LDFLAGS)
* extracting the .a archive to a temporary directory from the target  
Makefile and obtaining the names by `ls *.o` (similar to libtool)

Please decide what a patch should do to be accepted and to finally fix  
this issue.

Thanks,

Andreas
