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)

Using ld directly may break link-time optimization when that arrives.

Do not meddle in the internals of kernels, for they are subtle and quick to
