[yocto] Displaying buildcfg

[Chris Simmonds]

Hi,

At the start of a bitbake run it displays the current build
configuration before it starts to build anything:

Build Configuration:
BB_VERSION        = "1.28.0"
BUILD_SYS         = "x86_64-linux"
[...]

This information is useful, especially when you are swapping between
multiple projects with different versions. Is there a simple way to get
bitbake to print just this information, without going on to do build
anything?

Regards,
Chris
