Steps to re-create
------------------
Build a full eSDK for refkit-image-common
$ bitbake refkit-image-common -c populate_sdk_ext
Install it
$ refkit-x86_64-corei7-64-toolchain-ext-refkit.0.sh -d home/hbruce/refkit-sdk
Configure and try to get compiler version
$ cd home/hbruce/refkit-sdk
$ source environment-setup-corei7-64-refkit-linux
$ $CC -v
bash: x86_64-refkit-linux-gcc: command not found


Environment variables reference /home/hbruce/refkit-sdk/tmp/sysroots
Should be /home/hbruce/refkit-sdk/tmp-glibc/sysroots
$ echo $PATH

Does it work with poky? that 'tmp' part is hardcoded in meta-environment-extsdk.bb (OE-Core 4fe60d526a94f30b201c434994e80fef0f7392f0).

Seems it works with poky esdk. For some reason 'tmp' exists while for refkit the default 'tmp-glibc' remains.
Comment 3 Henry Bruce 2017-04-07 18:18:36 UTC 
It looks like an eSDk bug. In meta-environment-extsdk.bb commit 4fe60d5 sets TMPDIR=${TOPDIR}/tmp, should be TMPDIR=${TOPDIR}/tmp${TCLIBCAPPEND}.

I have patch ready that works with both poky+qemu and refkit, but not sure of the testing I need to do.
Comment 4 Paul Eggleton 2017-04-09 22:01:43 UTC 
FYI we are supposed to be forcing ${TOPDIR}/tmp to be the value as per:

ext-sdk-prepare.py still gets TMPDIR as 'tmp-glibc'.

Looks like defaultsetup.conf mangles TMPDIR still:

# Allow single libc distros to disable this code
TCLIBCAPPEND ?= "-${TCLIBC}"
TMPDIR .= "${TCLIBCAPPEND}"

poky has TCLIBCAPPEND="" so it works but we don't touch that.

Looks like TCLIBCAPPEND needs to be set to "" in populate_sdk_ext.bbclass if we want to force static 'tmp'.
