#     kbuild: deb-pkg: use build ID instead of debug link for dbg package
#     
#     There are two ways of managing separate debug info files:
#     
#      [1] The executable contains the .gnu_debuglink section, which specifies
#          the name and the CRC of the separate debug info file.
#     
#      [2] The executable contains a build ID, and the corresponding debug info
#          file is placed in the .build-id directory.
#     
#     We could do both, but the former, which 'make deb-pkg' currently does,
#     results in complicated installation steps because we need to manually
#     strip the debug sections, create debug links, and re-sign the modules.
#     Besides, it is not working with module compression.
#     
#     This commit abandons the approach [1], and instead opts for [2].
#     
#     Debian kernel commit de26137e2a9f ("Drop not needed extra step to add
#     debug links") also stopped adding debug links.
