Subject: [PATCH] Fix all-variables sysroot prefix problem

According to the pkg-config specifications (or rather documentation)
only the -L/-I directory entries should be sysroot-prefixed.

We also need to prefix the mapdir/sdkdir variables since they're used by
xorg and expected that way.

Also allow prefixing for includedir and libdir since in some silly cases
the directories may be requested barebones via pkg-config
--variable=includedir libfool for example.

Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar>

Added pkgdatadir to the list of to-be-prefixed variables.
