[EXT] [PATCH 2/2] devtools: configure source repo to use as ABI reference

[Akhil Goyal]

> By default 'test-meson-builds.sh' script clones the repository which the
> script is in, and selects a configured branch ('DPDK_ABI_REF_VERSION')
> as a reference for ABI check.
> 
> This patch enables selecting different repository to close for reference
> using 'DPDK_ABI_REF_SRC' environment variable.
> 
> It is possible to put these variables to 'devel.config' config file, or
> provide via command line, like:
> `
>  DPDK_ABI_REF_SRC=~/dpdk-stable/   \
>  DPDK_ABI_REF_VERSION=v22.11.1     \
>  DPDK_ABI_REF_DIR=/tmp/dpdk-abiref \
>  ./devtools/test-meson-builds.sh
> `
> 
> When 'DPDK_ABI_REF_SRC' is not defined, script behaves as it did
> previously.
> 
> Other alternative to using 'DPDK_ABI_REF_SRC' variable is adding that
> other repo as a new 'remote' to the exiting git repository.

Worked for me, but I still needed to clone the dpdk-stable repo manually.
I was hoping, test-meson-build.sh would do that by itself.
Had it been a tag in same repo, it would have been straight forward as before.
I would still suggest to add a tag v22.11.1 in main branch and all can use that instead of v22.11.
The fix that we are talking about is a mandatory one for each one to use for ABI checks,
dpdk-stable patches are not mandatory for the users.
