I am unhappy with ugly hacks in this Makefile.
(I could understand what is the hand-crafted .bpfilter_umh.o.cmd
used for.)

Moreover, CONFIG_OUTPUT_FORMAT is causing build errors
because it is defined only for x86.

As far as I understood, what is happening here is
to embed the 'bpfilter_umh' as a blob.
Instead, we can use '.incbin' to include it into a *.S file.

Also, let's stop (ab)using host-program rules.

Only build test is done.



Masahiro Yamada (3):
  bpfilter: add bpfilter_umh to .gitignore
  bpfilter: include bpfilter_umh in assembly instead of using objcopy
  bpfilter: do not (ab)use host-program build rule
