[PATCH 0 of 2] CACAO build fixes

[gnu_andrew at member.fsf.org]

The following two patches make changes to the CACAO build on IcedTea6.
The first includes a patch already in IcedTea7 so that CACAO works
again when compiled with GCC 4.4 on x86_64.  The second moves the
cacao patches to their own subdirectory, again as on IcedTea7.

Ok to commit?

Can we also backport the first patch to 1.5?
