[xml/sgml-pkgs] Bug#697382: libxml2-dev: libxml-2.0.pc misses -llzma for static linking

[Brice Goglin]

Package: libxml2-dev
Version: 2.9.0+dfsg1-4
Severity: normal

Dear Maintainer,

libxml-2.0.pc doesn't seem to be correct for static linking.

  $ pkg-config --libs --static libxml-2.0 
  -lxml2 -lz -lm  

It should bring a dependency on -llzma:

  /usr/lib/gcc/x86_64-linux-gnu/4.7/../../../x86_64-linux-gnu/
   libxml2.a(xzlib.o):function xz_decomp:
   error: undefined reference to 'lzma_code'

Either directly in Libs.private, or maybe as:
  Requires.private: liblzma

Thanks
Brice
