Merge tag 'kbuild-v4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild 

Pull more Kbuild updates from Masahiro Yamada:

 - add build_{menu,n,g,x}config targets for compile-testing Kconfig

 - fix and improve recursive dependency detection in Kconfig

 - fix parallel building of menuconfig/nconfig

 - fix syntax error in clang-version.sh

 - suppress distracting log from syncconfig

 - remove obsolete "rpm" target

 - remove VMLINUX_SYMBOL(_STR) macro entirely

 - fix microblaze build with CONFIG_DYNAMIC_FTRACE

 - move compiler test for dead code/data elimination to Kconfig

 - rename well-known LDFLAGS variable to KBUILD_LDFLAGS

 - misc fixes and cleanups

As a technical note, when directories and files are specified, the
entire CONFIG_INITRAMFS_SOURCE is passed to
scripts/gen_initramfs_list.sh. This means that CONFIG_INITRAMFS_SOURCE
usr/gen_initramfs_list.sh. This means that CONFIG_INITRAMFS_SOURCE
can really be interpreted as any legal argument to
gen_initramfs_list.sh. If a directory is specified as an argument then
the contents are scanned, uid/gid translation is performed, and
usr/gen_init_cpio file directives are output. If a directory is
specified as an argument to scripts/gen_initramfs_list.sh then the

contents of the file are simply copied to the output. All of the output
directives from directory scanning and file contents copying are
processed by usr/gen_init_cpio.

The kernel does not depend on external cpio tools. If you specify a
directory instead of a configuration file, the kernel's build infrastructure
creates a configuration file from that directory (usr/Makefile calls
scripts/gen_initramfs_list.sh), and proceeds to package up that directory

using the config file (by feeding it to usr/gen_init_cpio, which is created
