Infrastructure for packages with specific build systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By 'packages with specific build systems' we mean all the packages whose build
system is not the standard one, speak 'autotools'. This typically includes
packages whose build system is based on hand-written Makefiles or shell
scripts.

--------------------------------
The Makefile begins with line 4 with the inclusion of the top level rules.mk
file. After that the Makefile starts on line 6 to 15 with metadata
information: the name of the package (+PKG_NAME+), the version of the package
(+PKG_VERSION+), the release number of the package (+PKG_RELEASE+), which is
used in OpenADK to mark any package updates, the sha256 hash of the source archive
(+PKG_HASH+), the short one line description for the package (+PKG_DESCR+),
the package section for the menu configuration system (+PKG_SECTION+), the
package buildtime dependencies (+PKG_BUILDDEP+), the package runtime
dependencies (+PKG_DEPENDS+), the package homepage (+PKG_URL+) and finally the
internet locations at which the tarball can be downloaded from (+PKG_SITES+).
Normally ${PKG_NAME}-${PKG_VERSION}.tar.gz will be downloaded. You can
overwrite the default via the +DISTFILES+ variable. You can add more then one
archive name in +DISTFILES+ via space separated. If you have no source archive
at all, just use the boolean variable +NO_DISTFILES+ and set it to 1.
On line 17 the +mk/package.mk+ file is included, which contains the PKG_template
function, which is used in line 19.
On line 21 to 23 we define that the configuration step, the building and install
steps are manually provided.
On line 25-26 we implement a manual configuration step of the libfoo package
by copying a manually created config file into the build directory.
On line 28-29 we start the compilation process via make.
On line 31-33 we install the shared library into the package installation
directory, which is used to create the resulting binary package or tar archive
for the target.
On line 35 we include +mk/pkg-bottom.mk+, which includes common functions used
by the package fetching and building process.
