[PATCH 0/1] Grafting problem with libxml2

[Leo Famulari]

In 493e9a5a8f we fixed some bugs in libxml2 with a graft. Later, I
couldn't reconfigure my GuixSD system, due to an error like this:

ERROR: invalid replacement
"/gnu/store/3szw4bvhlm0pv9fm6vhmzzdj64d7gvr6-python2-libxml2-2.9.3"
"/gnu/store/5pp4pv6k8hhx2fgx62d40c028lszr8ga-libxml2-2.9.3"

Python-libxml2 inherits from libxml2, so it seems that it needs
(replacement #f), as in this patch.

With this patch, I can reconfigure my system. Also, python-libxml2 does
refer to the grafted libxml2, as expected:

$ ./pre-inst-env guix build --no-grafts libxml2
/gnu/store/7lxgrhmfgdd303gslaxazmmdv6n1nf77-libxml2-2.9.3

$ ./pre-inst-env guix build libxml2
/gnu/store/5pp4pv6k8hhx2fgx62d40c028lszr8ga-libxml2-2.9.3

$ guix gc --references $(./pre-inst-env guix build python-libxml2)
/gnu/store/5pp4pv6k8hhx2fgx62d40c028lszr8ga-libxml2-2.9.3

/gnu/store/v39bh3ln3ncnzhyw0kd12d46kww9747v-gcc-4.9.3-lib

It seems like the right thing to do to me. What do you think?
