Quentin Schulz 17c9deb115 utils/generate-cyclonedx: hint at missing Buildroot host package on a specific error
Since last commit, utils/generate-cyclonedx can now be used with
Buildroot host tools, provided the user either externally install the
SPDX schema in the DL_DIR themselves or have
BR2_PACKAGE_HOST_PYTHON3_SSL and BR2_PACKAGE_HOST_CA_CERTIFICATES both
enabled. If the latter is missing, Python will complain with:

Provide some hint as to what could be missing from Buildroot host.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at https://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on OFTC IRC.
