Subject: [PATCH v2] lib/build_OID_registry: Don't mention the full path of the script in output

This change strips the full path of the script generating
lib/oid_registry_data.c to just lib/build_OID_registry. The motivation
for this change is Yocto emitting a build warning

File /usr/src/debug/linux-lxatac/6.7-r0/lib/oid_registry_data.c in package linux-lxatac-src contains reference to TMPDIR [buildpaths]

So this change brings us one step closer to make the build result
reproducible independent of the build path.

- Handle abs_srctree not being exported any more

The v1 patch made it into next but im combination with commit e2bad142bb3d
("kbuild: unexport abs_srctree and abs_objtree") resulted in a build warning
about $ENV{"abs_srctree"} being uninitialized which required this respin.

Best regards
Uwe

I'd rather remove the script name from the comment or hard-code the
file name, but this is correct as it is.
