[PATCH 0/2] Fix TMPDIR usage in scripts v2

[PATCH 0/2] Fix TMPDIR usage in scripts v2

[Paul Eggleton]

Fix TMPDIR external environment variable usage within our scripts which
is a problem on OpenSUSE within an X session (see Yocto bug #1530) by
using OE_TMPDIR from the external environment instead.

Note that this will require changes to autobuilder scripts that use a
TMPDIR environment variable when calling these scripts - they should now
set OE_TMPDIR instead (if versions with and without this change need to
be run on the same system, then setting both variables will cause no
harm).

Since v1, also fix pass-through references to TMPDIR in the
qemuimage-testlib script.


The following changes since commit e0908b7b080c0d861a1b3ccb2185b9281b10fa1a:

[PATCH 1/2] scripts: use OE_TMPDIR instead of TMPDIR external variable

[Paul Eggleton]

On OpenSUSE within an X session, TMPDIR is set to the system temporary
directory (/tmp) which is incorrect for these scripts. Thus, change
runqemu and oe-setup-rpmrepo to use OE_TMPDIR from the external
environment rather than TMPDIR.

Fixes [YOCTO #1530]

[PATCH 2/2] scripts/oe-setup-rpmrepo: use setup_tmpdir from runqemu

[Paul Eggleton]

Update the internal copy of setup_tmpdir in the oe-setup-rpmrepo script
to be the same as the one in the runqemu script.

So I missed yet another reference in classes/. Please disregard this version.
