[OE-core] [PATCH][V2] u-boot: state the MACHINE when skipping u-boot

[Ross Burton]

If the user accidently tries building u-boot on a machine doesn't use u-boot
(such as qemuarm) the error message doesn't make it clear why u-boot was
skipped.  To help, state the machine that was being built for again.
