Already works for me here in 2.6.38.5:
  $ head -n 5 Makefile
  VERSION = 2
  PATCHLEVEL = 6
  SUBLEVEL = 38
  EXTRAVERSION = .5
  NAME = Flesh-Eating Bats with Fangs
  $ rm -rf FOO
  $ mkdir FOO
  $ make INSTALL_HDR_PATH=$(pwd)/FOO ARCH=x86 headers_install
  $ ls -l FOO
  total 4
  drwxr-xr-x 12 ymorin users 4096 2011-05-03 23:57 include
  $ cat FOO/include/linux/version.h
  #define LINUX_VERSION_CODE 132646
  #define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))
  $ make --version | head -n 1
  GNU Make 3.81

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
