Output a simple RPM spec file.

This version assumes a minimum of RPM 4.13

The only gothic bit here is redefining install_post to avoid

stripping the symbols from files in the kernel which we want

Patched for non-x86 by Opencon (L) 2002 opencon@rio.skydome.net

We can label the here-doc lines for conditional output to the spec file

%package headers
Summary: Header files for the Linux kernel for use by glibc
Group: Development/System
Obsoletes: kernel-headers
Provides: kernel-headers = %{version}
%description headers
Kernel-headers includes the C header files that specify the interface
between the Linux kernel and userspace libraries and programs.  The
header files define structures and constants that are needed for
building most standard programs and are also needed for rebuilding the
glibc package.
