Dexuan Cui be2a2764d8 oe-init-build-env, scripts/oe-buildenv-internal: add error detecting for $BDIR
[YOCTO #671]

"readlink -f" in Ubuntu 10.04 is buggy: it doesn't ignore a trailing / (e.g.,
"readlink -f /tmp/non-existent-dir/" returns nothing, but according to
http://www.gnu.org/s/coreutils/manual/coreutils.pdf it should do that --
hence we get bug 671. It seems Ubuntu 10.10 or even later Ubuntu 11.04,
and other Linux distributions(e.g., Open Suse 11.4) haven't such an issue.

So I think we should detect this and ask Ubuntu 10.04 users to avoid supply
a path with trailing slash here.

Moreever, I also add the detection of non-existent path, e.g.,
source oe-init-build-env /non-existent-dir/build
can be detected and we'll print an error msg.
And, if we get errors in oe-buildenv-internal, we should stop the script
and shouldn't further run.
