Originally this was choosen because most packages were -not- using 
pkglibexecdir.  This was causing a libexecdir that was containing multiple, 
sometimes conflicting binary names.

So the fix was either patch the recipes to add their BPN, or just add the BPN to 
the libexecdir itself.

Personally I think using "${exec_prefix}/libexec" is incorrect.  This does not 
support a multilib configuration where you may have both a 64-bit and 32-bit 
version of the libexec program on the system.  (perhaps this isn't a real 
problem, but we ran into some conflicts in the past.)

So moving to the libdir, ensures that we are unique per multilib.. and the BPN 
ensures that we're unique per recipe.
