These files were taken from the Linux Kernel Configuration System at commit
089b7d890f972f6b649fedc9259f6b93a18fb970 (Feb 4, 2020) and modified for the
OpenWrt Buildroot:
- removed nconf, gconf, tests and kernel configuration targets
- adjusted the Makefile to compile outside the kernel
- always use default file when running make all{no,mod,yes}config
- added a 'reset' command to reset config when the target changes
- allow config reading from & writing to a different file
- allow 'source' command to use globs to include multiple files
- don't write auto.conf and other files under include/ directory
- reverted a commit to allow use of '/' & '.' in unquoted config symbols.
There are too many of those in OpenWrt right now.
- reverted a commit that was issuing a warning when there were more than
one help text. This is used in a few packages to use different texts
for the menuconfig help, and the ipkg package description.
- reverted an upstream change that avoids writing symbols that are not
visible to .config, which breaks OpenWrt busybox's '.config' generation
logic.
- add a compilation option (-DWARN_RECURSIVE_DEP) to treat recursive deps
as a warning, avoiding a complete build failure because of unrelated or
minor recursive deps, or making a scrict check before commiting a change
that may cause one.
- use pre-built *.lex.c *.tab.[ch] files by default, to avoid depending on
flex & bison. Rebuild/remove these files only if running make with
BUILD_SHIPPED_FILES defined.
- allow a bool symbol to select a tristate symbol that depends on m (i.e.
a package that should only be built as a module).
