[Xen-devel] [PATCH] tools: fix python install with "xentoollog"

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

commit 5d3dc8671521ea4a4f753e77d3e7fb3a3a6f5f80
"tools: Refactor "xentoollog" into its own library"
with older python versions (2.6.4) will fail to
the build if attempted to be done twice (which
happens due to pygrub dependencies).

make -C python DESTDIR=/tmp
make -C python DESTDIR=/tmp

The second one will fail with:
error: -Wl, -rpath-link=../../tools/libs/toollog: No such file or directory

even thought the directory is there (with the libs).

Andrew pointed out that the linker additions should be in
the "extra_link_args" rather than "depends".

And true enough - with that modification it builds.
