Re: [OE-core] mesa-native fails on master

[Mark Hatle <mark.hatle@kernel.crashing.org>]

I'm fine with saying either Ubuntu 18.04 is no longer 'supported', or running 
some kind of check that says gcc 7.5.0 is too old..  But I'm not sure what 
minimum (host) compiler version would be needed to avoid this error.

I'm happy to work up a patch to adjust the minimum gcc version, if someone can 
give me a bit of a clue what the appropriate minimum should be.

The current check (in sanity.bbclass) looks for 7.5 or newer.
