packageinfo.bbclass : extended functionality

Extended the functionality of packageinfo.bbclass
so that the sistem retrieves information about the
files brought in by each package. This is done
(without activating buildhistory) by parsing
the packages-split directory for each package.

elfutils: remove i386_dis.h/x86_64_dis.h compilation targets

Since we provide those files manually (i386_gendis, which is needed for
generating those files, has to be run on host and would fail when
compiling for other architectures), the mentioned compilation targets
in libcpu/ are not needed anymore.

This change will avoid a nasty race condition when running "make -jX
install" resulting in a zero size libebl_i386.so file. The issue happens
because, at "make install" time, the *_dis.h prerequisites will be newer
than the target itself, triggering a chain of recompilations while, in
the same time, the binary files are copied to the destination directory.
Hence, the zero sized file...
