#     kbuild: remove cc-option switch from -Wframe-larger-than=
#     
#     This CONFIG option was added by commit 35bb5b1e0e84 ("Add option to
#     enable -Wframe-larger-than= on gcc 4.4"). At that time, the cc-option
#     check was needed.
#     
#     According to Documentation/process/changes.rst, the current minimal
#     supported version of GCC is 4.6, so you can assume GCC supports it.
#     Clang supports it as well.
#     
#     Remove the cc-option switch and redundant comments.
