Works for me too :) I was trying:

echo 'INSTALL_HDR_PATH=$RPM_BUILD_ROOT/usr make %{?_smp_mflags} headers_install'

along the lines of:

scripts/packaging/mkspec:

echo 'INSTALL_MOD_PATH=$RPM_BUILD_ROOT make %{?_smp_mflags} KBUILD_SRC=modules_install'

While we're on the topic, could we enhance mkspec to spit out -devel and
-headers rpms too? I can post patches if there is sufficient interest.

It'd be nice to use the same mechanism to define/override:

INSTALL_PATH
INSTALL_MOD_PATH
INSTALL_HDR_PATH
