#     Makefile: Do not quote value for CONFIG_CC_IMPLICIT_FALLTHROUGH
#     
#     Andreas reported that a specific build environment for an external
#     module, being a bit broken, does pass CC_IMPLICIT_FALLTHROUGH quoted as
#     argument to gcc, causing an error
#     
#       gcc-11: error: "-Wimplicit-fallthrough=5": linker input file not found: No such file or directory
#     
#     Until this is more generally fixed as outlined in [1], by fixing
#     scripts/link-vmlinux.sh, scripts/gen_autoksyms.sh, etc to not directly
#     include the include/config/auto.conf, and in a second step, change
#     Kconfig to generate the auto.conf without "", workaround the issue by
#     explicitly unquoting CC_IMPLICIT_FALLTHROUGH.
