#     kbuild: Use -fmin-function-alignment when available
#     
#     GCC recently added option -fmin-function-alignment, which should appear
#     in GCC 14. Unlike -falign-functions, this option causes all functions to
#     be aligned at the specified value, including the cold ones.
#     
#     In particular, when an arm64 kernel is built with
#     DYNAMIC_FTRACE_WITH_CALL_OPS=y, the 8-byte function alignment is
#     required for correct functionality. This was done by -falign-functions=8
#     and having workarounds in the kernel to force the compiler to follow
#     this alignment. The new -fmin-function-alignment option directly
#     guarantees it.
#     
#     Detect availability of -fmin-function-alignment and use it instead of
#     -falign-functions when present. Introduce CC_HAS_SANE_FUNCTION_ALIGNMENT
#     and enable __cold to work as expected when it is set.
