In some cases when packaging it may not be useful to build kmod/core at
package build time (for example if using DKMS). Add a parameter 'BUILDMOD'
that when set to 'yes' will build kmod/core.

Some distributions prefer not to use /usr/libexec. To make things easier
for packaging, allow this directory to be set easily via environment
variables.

On RHEL I'm seeing issues with putting the core module in the "extra"
path. On the next depmod run, it gets added to modules.dep, and on a
subsequent kpatch install I see the following errors:
/usr/lib/dracut/modules.d/50drm/module-setup.sh: line 26: /lib/modules/3.10.0-123.4.4.el7.x86_64//weak-updates/kpatch/kpatch.ko: No such file or directory
/usr/lib/dracut/modules.d/90kernel-modules/module-setup.sh: line 14: /lib/modules/3.10.0-123.4.4.el7.x86_64//weak-updates/kpatch/kpatch.ko: No such file or directory
modinfo: ERROR: Module /lib/modules/3.10.0-123.4.4.el7.x86_64/weak-updates/kpatch/kpatch.ko not found.
Until the core module gets merged into Linux, I think we can put it in
/usr/lib/kpatch, which is also where the patch modules are going to be
delivered in the RHEL RPM.
Making sure the other options still work with the kpatch utility for
now, so as to keep backwards compatibility between a newer kpatch
utility and older core modules. We can break this compatibility for
kpatch 0.2.0.
User reported cases where libraries are in lib32/64 directories, not
lib.
Allow the user to override by setting LIBDIR.

Unforunately the dracut module doesn't work if installed in
/usr/local/lib/dracut. It must always be installed in
/usr/lib/dracut regardless of the install prefix.
kpatch-build is outgrowing the kpatch script and probably is a better
fit as its own utility instead of being wrapped by kpatch. Install
kpatch-build into /usr/local/bin, remove the kpatch wrapper around it,
and update the README accordingly.
Build and install the kpatch core module with make and make install,
rather than building it every time with kpatch build.
The only downside to this approach is that the user has to make and make
install kpatch every time they get a new kernel. But this is only
temporary, until the kpatch module is delivered in an RPM.
- setup the makefiles to support "make" and "make install", which builds
the kpatch-build tools and installs everything in /usr/local.
- update kpatch-build to support new paths
- add "kpatch build" wrapper around kpatch-build
