Issue Compiling syncd-brcm on SONiC Commit cb707b7969c8f3f34d7134a661c7a6ca3f076d3b: Missing libsaibcm_7.1.7.2_amd64.deb

[Kiran-nokia]

Hello SONiC Community,

I am attempting to build SONiC using the following commit:
cb707b7

When I run the command:
SONIC_BUILD_JOBS=2 make target/docker-syncd-brcm.gz

I encounter the following error:

[ FAIL LOG START ] [ target/debs/bullseye/libsaibcm_7.1.7.2_amd64.deb ]
[ REASON ] : target/debs/bullseye/libsaibcm_7.1.7.2_amd64.deb does not exist
[ FLAGS FILE ] : []
[ FLAGS DEPENDS ] : []
[ FLAGS DIFF ] : []
curl: (37) Couldn't open file /tmp/libsaibcm_7.1.7.2_amd64.deb
[ FAIL LOG END ] [ target/debs/bullseye/libsaibcm_7.1.7.2_amd64.deb ]
make: *** [slave.mk:525: target/debs/bullseye/libsaibcm_7.1.7.2_amd64.deb] Error 1

I have the libsaibcm_7.1.7.2_amd64.deb file from a previous download and have tried placing it in tmp as well as target/debs/bullseye/, but the build system still attempts to fetch it via curl and fails.

Could anyone advise:

The correct way to use a locally available .deb file for this build?
If there is a recommended workaround for this version?
If the file is available from any official or community source?
Any guidance would be greatly appreciated!

Thanks
Kiran
