  kconfig: add optional warnings for changed input values (2026-06-18 11:46:32 -0700)

----------------------------------------------------------------
Second round of Kbuild changes for 7.2

- Link host programs with ld.lld when $(LLVM) is set to match user's
  expectations that LLVM will be used exclusively during the build
  process

- Fix modpost warnings from static variable name promotion that can
  happen more aggressively with the recently merged distributed ThinLTO
  support

- Add an optional warning for user-supplied Kconfig values that changed
  after processing, such as out of range values or options that have
  incorrect / missing dependencies
