Mark Hatle 60ccdaa0ea poky-init-build-env: Enable all POSIX shells

Update the script so that it will work in more then just bash.  If bash
is not used, it will assume the PWD is the Poky location.  (This is because
BASH_SOURCE is a bash-ism, and equivalent functionality is not available in
other shells).

This has been verified with dash (see comment in the code), ksh, zsh and
of course bash.

Normally this is called as '. ./poky-init-buildenv builddir'

This works in most shells (not dash), but not all of them pass arg1 when

being sourced. To workaround the shell limitation use "set arg1" prior

to sourcing this script.

if [ "x$0" = "x./poky-init-build-env" ]; then echo "Error: This script needs to be sourced. Please run as '. ./poky-init-build-env'" else if [ -n "$BASH_SOURCE" ]; then OEROOT="dirname $BASH_SOURCE" else OEROOT="pwd" fi OEROOT=readlink -f "$OEROOT" export OEROOT . $OEROOT/scripts/poky-env-internal $OEROOT/scripts/poky-setup-builddir unset OEROOT [ -n "$BUILDDIR" ] && cd $BUILDDIR fi
