[Qemu-devel] [PATCH 2/3] Makefile: Fix 'make distclean'

[Peter Maydell]

We forgot the '-r' option on the rm command to clean up the
Sphinx .doctrees working directory, which meant that
"make distclean" fails:
 rm: cannot remove '.doctrees': Is a directory

Add the missing option.

Fixes: 5f71eac06e15b9a3fa1134d446f ("Makefile, configure: Support building rST 
documentation")
