Stuart,
I did the same thing, but controlled it with
"PKG_CONFIG_WANT_HEADERS_INSTALL" to allow the platform to select "make
headers_install" instead of the current method, then if a platform wants
"make headers_install" it just has to define
PKG_CONFIG_WANT_HEADERS_INSTALL in its main.lkc...
When you say "copy this to the platform specific dir", do you mean to
copy the whole kernel-common.tmpl to the config/platform/<platform>
directory?
