[bitbake-devel] [PATCH 1/1] tinfoil.py: Check if BUILDDIR exists

[Amanda Brindle]

Check if BUILDDIR exists in order to deterimine if a tinfoil using
script is running without having called oe-init-build-env (or similar).
If not, instruct user to initialise the build environment, and then
error out immediately. Before, tinfoil would hang for 30s before
erroring out.

Fixes [YOCTO #12096]
