[OE-core] [PATCH 1/6] scripts/bitbake: ensure user is in build directory

this patch broke my setup.

My $BUILDDIR points to tmp, so that pseudo doesn't get rebuilt for every
machine. I have a shared tmp for many machines.

BUILDDIR doesn't seem to have any other use than pointing to the
'pseudodone' file. I don't understand why it's required to run bitbake
from there.

I'm using a tiny shell fragment to set up my build environment. This is
how it looks like:

export BUILDDIR=${PREFIX}/tmp
export
PATH=${PREFIX}/openembedded-core/scripts:${PREFIX}/bitbake/bin:${PATH}

local.conf and bblayers.conf for individual machines are stored in
${PREFIX}/build/${MACHINE}/conf.

Regards,
Andreas
