[OE-core] [PATCH 0/4][RFT] Stop disabling autoheader warnings

[Ross Burton]

Hi,

When autoheader emits a warning along the lines of "missing template for
variable HAVE_FOO", it's not moaning that you need to be more verbose for nice
comments in the config.h files.  In fact it's saying that it's not writing that
symbol at all to config.h.in, so even if that test succeeds this isn't reflected
in config.h.

I removed the patch and did a build of core-image-sato: readline was the only
recipe that failed.  I'll spare you the anger but readline is special...  the
short version is that if an upstream package hand-maintains config.h.in instead
of using autoheader then set EXTRA_AUTORECONF += "--exclude=autoheader" and
autoheader won't be executed.

This is also a call out for a request for testing: I've done a core-image-sato
build with this but haven't yet done world or any other layers.  If there's
breakage it's often due to the upstream being unconventional so feel free to
prod me for help.
