[xml/sgml-pkgs] Bug#826130: libxml2: FTBFS on i386

[Salvatore Bonaccorso]

Source: libxml2
Version: 2.9.3+dfsg1-1
Severity: serious
Justification: FTBFS

The recent 2.9.3+dfsg1-1.1  upload of src:libxml2 FTBFS on i386:

https://buildd.debian.org/status/fetch.php?pkg=libxml2&arch=i386&ver=2.9.3%2Bdfsg1-1.1&stamp=1464849314

I tested the build on barriere.d.o, and this already happens with
2.9.3+dfsg1-1 though with:
