  scripts/Kconfig.toolchain: Highlight cc-option differences between Kconfig and Kbuild (2026-10-20 14:55:40 -0700)

----------------------------------------------------------------
First round of Kbuild fixes for 7.4

- Move probing of '-mfentry' back into Makefile instead of Kconfig
  because it does not interact well with toolchains that support
  multiple bit widths

- Add a big comment in scripts/Kconfig.toolchain of two pitfalls when
  moving cc-option checks from Kbuild to Kconfig
