Haixiao Yan e3ce89324d buildtools-tarball: fix unbound variable issues under 'set -u'
When Bash runs with 'set -u' (nounset), accessing an unset variable
directly (e.g. [ -z "$SSL_CERT_FILE" ]) causes a fatal "unbound variable"
error. As a result, the fallback logic to set SSL_CERT_FILE/SSL_CERT_DIR
is never triggered and the script aborts.

The current code assumes these variables may be unset or empty, but does
not guard against 'set -u'. This breaks builds in stricter shell
environments or when users explicitly enable 'set -u'.

Fix this by using parameter expansion with a default value, e.g.
"${SSL_CERT_FILE:-}", so that unset variables are treated as empty
strings. This preserves the intended logic (respect host env first, then
CAFILE/CAPATH, then buildtools defaults) and makes the script robust
under 'set -u'.

Poky

Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.

Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.

As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.

The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/

OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Contribution Guidelines

Please refer to our contributor guide here: https://docs.yoctoproject.org/dev/contributor-guide/ for full details on how to submit changes.

Where to Send Patches

As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:

OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):

BitBake (files in bitbake/):

Documentation (files in documentation/):

meta-yocto (files in meta-poky/, meta-yocto-bsp/):

If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
