I didn't add BSP patch support for Linux, Stephen did,
but already before the BSP patch, the Linux was built
in a separate dir if the the kernel version was not the same
as the kernel-headers.

The kernel headers are installed in $(STAGING_DIR) and 
with the BSP patch you can have a separate kernel source directory for
each special configuration of the kernel, so the current kernel is 
installed in $(PROJECT_BUILD_DIR)/linux-$(LINUX26_VERSION)

The kernel in $(PROJECT_BUILD_DIR) does not get patched with openswan,
and even when a separate kernel source was built in $(BUILD_DIR), 
it did not get patched unless the kernel version was the same as the kernel header version.

I assume that this means we have to update target/linux/Makefile.in...

I also noted that the openswan patches are rather large.
Maybe we should have them downloadable from some location
instead of part of the buildroot trunk.
Each patchset for a kernel version is close to 2 MB.
