Hi Kees,

Doing a "make help" would show only hard-coded Kconfig targets and
depended on the archhelp target to include ".config" targets. There was
nothing showing global kernel/configs/ targets. Solve this by walking
the wildcard list and include them in the output, using the first comment
line as the help text.

Update all Kconfig fragments to include help text and adjust archhelp
targets to avoid redundancy.

Adds the following section to "help" target output:

Configuration fragment targets (for enabling various Kconfig items):
  debug.config         - Debugging for CI systems and finding regressions
  kvm_guest.config     - Bootable as a KVM guest
  nopm.config          - Disable Power Management
  rust.config          - Enable Rust
  tiny-base.config     - Minimal options for tiny systems
  tiny.config          - Smallest possible kernel image
  x86_debug.config     - Debugging options for tip tree testing
  xen.config           - Bootable as a Xen guest
  tiny.config          - x86-specific options for a small kernel image
  xen.config           - x86-specific options for a Xen virtualization guest
ISTM that you are missing the "why" part of this change in the commit
description.

"make tinyconfig" is the real target here.  The other (tiny.) files are just
implementation details.
We can't put all implementation details into help messages and it's not
difficult to find that the (tiny.) config files are merged to make the
final .config file.

So what is it that you are trying to solve?
