[BProc] a packaging issue in bproc-4.0.0pre5

[Michal J. <mi...@ha...>]

Changes in Makefiles mean that vmadump kernel module is installed
somewhat indirectly.  An unfortunate side-effect of that is that
vmadump.h header is no longer installed in /usr/include/sys.
This prevents compilation of things like cmtools and beoboot as they
want to see that header.  This is likely harder to notice when
you have "historical" headers present but hits when you are doing
that from scratch.

There are likely various ways to get around that.  I just split
an 'install' target in vmadump/Makefile into 'install-headers'
and 'install', which depend on the first, and in the top Makefile
added to INSTALL_TARGETS something which does
'$(MAKE) -C vmadump install-headers' and things are fine again.

BTW - "BuildRequires:" in beboot.spec for beoboot-cm1.9 needs
both cmtools-devel and bproc-devel as headers from both packages
are used.

Another note - a default value for LINUX in various spec files
should really be /lib/modules/$(uname -r)/build instead of
/usr/src/linux.  Nowadays you will not find what is needed in
the later, and similar, locations while data required for building
external modules for the current kernel should be there under
/lib/modules/$(uname -r)/build - be that a symlink or an actual
directory.
