  There should be an empty line here.

  No . in the beginning of the path, it's the absolute path on the target.

  Wrap at 72 columns (where the tab counts for 8).

  It also seems to need:

	select BR2_PACKAGE_ARGP_STANDALONE if !BR2_TOOLCHAIN_USES_GLIBC

  For some reason, it doesn't seem to be cross-compiling for me, it uses "gcc" 
to build. I think you need to pass TARGET_CONFIGURE_OPTS in XEN_MAKE_ENV.

  Commands should be indented with a tab.
