[PATCH] D48459: Respect CMAKE_SYSROOT and CMAKE_CROSSCOMPILING when searching for libxml2.

Ah, the documentation is confusing, but CMAKE_FIND_ROOT_PATH and CMAKE_FIND_ROOT_PATH_MODE_PACKAGE only have an effect when using the config mode of find_package, whereas this invocation is using the module mode. That's a bummer, and definitely makes custom sysroots and cross-compilation harder than it should be. Sorry for the noise.
