Hi,
Please see my comments in-line.

If I understand you correctly we have something like this already [3].
Used for example at [4].
Or did I got something wrong?
I think this is along the lines of what I want.

Why do we need to use "custom" meta-java stuff instead of what's already
available from OE out of the box?
HOST_COMPILER_MAJOR="${@oe.utils.get_host_compiler_version(d)[1].split(".",
2)[0]}"
CFLAGS_append = " ${@oe.utils.conditional('HOST_COMPILER_MAJOR', '9',
'-Wno-error=format-overflow', '', d)}"
works for me.
... and ...
It looks like your and my build environment with gcc-9 (RH) and gcc-9
(UB) behave differently?
This is totally crazy. Not only do we have a host compiler dependency
with meta-java, but also 9.2 vs. 9.3 and maybe RH and UB hacked
different things there?
Also we are just turning off warnings/errors, in this case buffer
overflows, instead of fixing them, which is not good as well. So the
problem might also be in some library/header or so. But I guess with
OpenJDK to fix those it's another cup of tea.
... or ...
somewhere magic host CFLAGS are being added.
... one more thing ...
Do you think it should work on one of those distros out of the box, so I
can try to reproduce what you have on my end?

How is meta-java usually tested?
