We will maintain only the 5.4 kernel for dunfell LTS. Switch alt-cfg to
using v5.4.

-Subject: [PATCH] menuconfig,check-lxdiaglog.sh: Allow specification of ncurses
- location
-
-In some cross build environments such as the Yocto Project build
-environment it provides an ncurses library that is compiled
-differently than the host's version.  This causes display corruption
-problems when the host's curses includes are used instead of the
-includes from the provided compiler are overridden.  There is a second
-case where there is no curses libraries at all on the host system and
-menuconfig will just fail entirely.
-
-The solution is simply to allow an override variable in
-check-lxdialog.sh for environments such as the Yocto Project.  Adding
-a CROSS_CURSES_LIB and CROSS_CURSES_INC solves the issue and allowing
-compiling and linking against the right headers and libraries.
-

-Subject: [PATCH] perf: Make perf able to build with latest libbfd
-
-libbfd has changed the bfd_section_* macros to inline functions
-bfd_section_<field> since 2019-09-18. See below two commits:
-  o http://www.sourceware.org/ml/gdb-cvs/2019-09/msg00064.html
-  o https://www.sourceware.org/ml/gdb-cvs/2019-09/msg00072.html
-
-This fix make perf able to build with both old and new libbfd.
