Yeah, this is obviously not related to that change. As far as I can
tell, this means that the version of LLVM was compiled in an environment
without zlib. However, I am super confused because linux-5.4.y does not
even have commit 10e68b02c861 ("Makefile: support compressed debug
info") so we should not even be generating compressed debug sections in
the first place...

If I understand the robot's build script correctly, this should be clang
as the compiler and GNU as as the assembler. Is the version of GNU as
the robot is using built with '--enable-compressed-debug-sections',
which would turn compressed debug sections on by default? If so, we
should be able to override that by specifying '-gz=none' explicitly in
linux-5.4.y and earlier.
