Prelinking on x86-64 wasn't working out the box as it uses /lib and
not /lib64 for libs. Prelink was refusing to link as the dynamic loader
didn't match its idea of the right path. Passing in the --dyanmic-linker
option avoids this.
We can share code from image-mklibs so abstract that into a new class,
linuxloader.bbclass.
This does break prelinking of multilib images, I've opened a bug so we
can loop back and fix that problem, the code would need to iterate the
dynamic loaders (and setup ld.so.conf files for it).

Prelink contains some hardcoded assumptions about the path layout of
the target system. Unfortunately if the system doesn't match, prelink
doesn't work. This breaks:
a) prelink of those images
b) the unsafe-references-in-binaries QA test (which uses prelink-rtld)
One way to work around this is to construct an ld.so.conf file which
lists the library paths in question. We do this in sanity QA check and
in the rootfs prelink code, being careful not to trample any existing
target ld.so.conf.
There is an additional problem that $LIB references in RPATHs won't be
handled correctly, I've not see any system use these in reality though
so this change at least improves things.

I'm sick of seeing people adding to EXPORT_FUNCTIONS in these classes
when they clearly have no idea what it does.
Worse, these uses of it are all broken, the naming is incorrect and
they do nothing. Lets remove them and try and preserve any remaining
part of my sanity.

Pass -N option to prelink so that no cache file is generated (obviates need for deleting it afterwards).
Use symbolic names, ${sysconfdir} et al., rather than hardcoded paths.
Pass explicit -c option to prelink in case ${sysconfdir} and ${sysconfdir_native} are different.

RPM has the ability to validate files that have been prelinked, however
the necessary configuration and staging was not done properly. Resolve
this issue by fixing the macro paths, providing the missing RPM macro,
and correcting a defect in the way the prelink image class was working
with the necessary configuration file.

Add the ability to specify user level classes via the local.conf.
Use this new capability to add an image-prelink class that does an
image wide cross-prelink activity.
