This patch updates Kconfig to a more recent version of Kconfig, found
in Linux v5.4.0, 219d54332a09 ("Linux 5.4").
With the updated version of Kconfig, other changes are necessary to
avoid breaking the build.
Kconfig files:
- fix Kconfig files that where using option env=*:
Since Linux commit 104daea149c4 ("kconfig: reference environment
variables directly and remove 'option env='"), we can access the
environment directly via $() and "option env=" as been removed.
- CONFIG_EXPERT='y' will now appear in .config file if
XEN_CONFIG_EXPERT=y in the environment. The alternative is to change
"EXPERT" to "$(XEN_CONFIG_EXPERT)" in all Kconfig files.
Makefile:
- silentoldconfig target as been removed from Kconfig. To update
include/generated/autoconf.h, we need to use syncconfig target
instead.
Makefile.kconfig:
- Import newer needed code from Linux's Makefile.lib and
Kbuild.include and Makefile.build.
- Set Q to empty, Xen build system doesn't silence commands. Having Q
empty mean we can import stuff from Linux without having to remove the
leading $(Q) from build commands. And quiet='' means commands will be
echoed.
- Add $(PHONY) to .PHONY. Like it is intended by Kbuild.
Makefile.host is also updated and copied from Linux.
Dependency change:
- Now depends on flex/bison, maybe we could _shipped those files like
before. Linux doesn't do that anymore.
The .gitignore in kconfig/ has more entries, compared to upstream, for
file generated by Makefile.host.
