[libvirt] [PATCH 1/2] build: avoid non-srcdir installation failure (apibuild.py)

[Eric Blake]

According to Jim Meyering on 2/24/2010 6:20 AM:
> Running "make distcheck" from a non-srcdir build was failing like this:
> 
>     /bin/sh: ./apibuild.py: No such file or directory
> 
> Fixed that with the first patch below (the apibuild.py script
> is not in ".", but in $(srcdir)).
> 
> Then retrying, it got a little further but failed like this:
> 
>     (../../docs/apibuild.py)
>     make[3]: *** No rule to make target `sitemap.html.in', needed by `html/index.html'.  Stop.
> 
> That was because sitemap.html.in was not being distributed.
> Adding it to EXTRA_DIST solved that:

Why the subshell?
