Makefile: add kabi targets
Add make wrappers on redhat/kabi/{diff,update}-kabi and
redhat/kabi/symtypes:
- dist-kabi-update updates the stablelist checksums
- dist-symtype-diff diffs the current state against a reference
stored in the stablelist
- dist-kabi-image-NODE and dist-kabi-preimage-NODE dump the
image or preimage for a symtypes node (where NODE is either
an exported symbol, or a node representing a type, e.g.,
s#kobject).
A helper target called dist-assert-cross-tools is added to ensure
that cross compilation toolchain is available prior to execution
to ensure correct results.
