[OE-core] Status of meson cross compilation files in the SDK

[Carlos Rafael Giani]

Last I've checked, deploying meson cross compilation files with a Yocto 
SDK is tricky because that meson file has to be generated during SDK set 
up and because meson assumes that environment variables like $CC refer 
to the native host compiler.

Has anything changed? I have some bits of code here that use meson, and 
cross compiling them with the SDK has been difficult at best.
