If your layer has gcc_8.2.bbappend and the recipe in oe-core gets
renamed from gcc_8.2.bb to gcc_8.3.bb in newer thud revision, then your
bbappend will not apply and bitbake will complain that there is no
recipe for your gcc_8.2.bbappend.

Layer which doesn't even parse correctly with different revisions of
the same thud branch isn't really something we should encourage.

gcc_8%.bbappend with some logic inside (e.g. adding some .patch file
only when PV starts with 8.2) will be compatible with both newer and
older revision of thud.
