Merge tag 'kbuild-7.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux
Pull more Kbuild updates from Nathan Chancellor:
- 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
* tag 'kbuild-7.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linux:
kconfig: add optional warnings for changed input values
modpost: Ignore Clang LTO suffixes in symbol matching
kbuild: Use ld.lld for linking host programs when LLVM is set
