    Fix cross-compilation
    
    When cross-compiling against a sysroot for instance, a --sysroot option
    is typically passed via the CPPFLAGS variable. This can cause the build
    to break in the util subdirectory which requires the CPPFLAGS to be set
    for the build system.
    
    Solve this by using the value of CPPFLAGS_FOR_BUILD for CPPFLAGS in the
    util subdirectory. Cross-compile setups can override the variable when
    calling the configure script.
