To be used when cross-compiling to Raspbian without proper cross-compilation
packages that would contain the necessary headers and libraries.

+# When lacking a proper cross-compilation package system from Linux
+# (or some other Unix) to Raspbian, instead create a tarball of
+# headers, libraries and pkg-config files on a Raspbian system and
+# unpack that then on the build system, and pass in a -sysroot switch
+# to the cross-compiler.
