Merge tag 'kbuild-v5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild 

Pull Kbuild updates from Masahiro Yamada:

 - remove unneeded asm headers from hexagon, ia64

 - add 'dir-pkg' target, which works like 'tar-pkg' but skips archiving

 - add 'helpnewconfig' target, which shows help for new CONFIG options

 - support 'make nsdeps' for external modules

 - make rebuilds faster by deleting $(wildcard $^) checks

 - remove compile tests for kernel-space headers

 - refactor modpost to simplify modversion handling

 - make single target builds faster

 - optimize and clean up scripts/kallsyms.c

 - refactor various Makefiles and scripts

	In this example, extra-y is used to list object files that

	shall be built, but shall not be linked as part of built-in.a.



    header-test-y



	header-test-y specifies headers (`*.h`) in the current directory that

	should be compile tested to ensure they are self-contained,

	i.e. compilable as standalone units. If CONFIG_HEADER_TEST is enabled,

	this builds them as part of extra-y.



    header-test-pattern-y



	This works as a weaker version of header-test-y, and accepts wildcard

	patterns. The typical usage is::



		header-test-pattern-y += *.h



	This specifies all the files that matches to `*.h` in the current

	directory, but the files in 'header-test-' are excluded.
