Masahiro Yamada 5410b2c232 kbuild: refactor cross-compiling linux-headers package 
Since commit 13b25489b6 ("kbuild: change working directory to external
module directory with M="), when cross-building host programs for the
linux-headers package, the "Entering directory" and "Leaving directory"
messages appear multiple times, and each object path shown is relative
to the working directory. This makes it difficult to track which objects
are being rebuilt.

In hindsight, using the external module build (M=) was not a good idea.

This commit simplifies the script by leveraging the run-command target,
resulting in a cleaner build log again.
