rapidxml: add patch to fix usage with gcc 4.7+

The official `rapidxml` package release only supports up to GCC 4.6.x
for all capabilities. Implementers attempting to include the file
"rapidxml_print.hpp" will all result in a compilation failure when using
a currently supported Buildroot GCC version (all 4.7+ at this time).
With the provided patch, dependent packages will be able to use all of
rapidxml's capabilities using a generated toolchain from Buildroot (let
alone external toolchains).

[Thomas: rework patch so that it contains the proper line endings, and
applies properly without a pre-patch hook to convert the line endings
beforehand.]

[PATCH] ensure internal print operations are declared before use
Stock rapidxml-1.13 does not allow implementers of the
`rapidxml_print.hpp` header to build under GCC 4.7 (or newer) due to
compliation issues. This is a result of "Name lookup changes" introduced
in GCC 4.7 [1]. The following adds forward declarations required to
compile with GCC 4.7+.
This issue has been mentioned upstream [2], but it has yet to be fixed
in official sources.
