Subject: [PATCH 00/16] kbuild: support 'userprogs' syntax
Several Makefiles use 'hostprogs' for building the code for
the host architecture is not appropriate.
This is just because Kbuild does not provide the syntax to do it.
This series introduce 'userprogs' syntax and use it from
sample and bpf Makefiles.
Sam worked on this in 2014.
https://lkml.org/lkml/2014/7/13/154
He used 'uapiprogs-y' but I just thought the meaning of
"UAPI programs" is unclear.
Naming is one the most difficult parts of this.
I chose 'userprogs'.
Anothor choice I had in my mind was 'targetprogs'.
If you can test this series quickly by
'make allmodconfig samples/'
When building objects for userspace, [U] is displayed.
