[PATCH] prefix sysroot to include/libdir path variables

Prefix includedir / libdir variable values with sysroot if a variable is
requested (--variable=<name>), similar to how it's done for -I / -L flags.

This is sometimes used to find header files (E.G. in gst-plugins configure),
so ensure the sysroot'ed files are used.
