[Bug 987502] Re: libxml2-dev: /usr/bin/xml2-config isn't identical across all arch

[Aron Xu]

** Description changed:

- In the M-A implementation of version 2.7.8.dfsg-5.1ubuntu1,
+ [Background] In the M-A implementation of version 2.7.8.dfsg-5.1ubuntu1,
  /usr/bin/xml2-config still contains M-A tripples, which is troublesome
  when the package libxml2-dev is marked as M-A: same. The problem is
  caused by the sed call in debian/rules says "usr/lib/<tripple>", while
  it wasn't like that in xml2-config script itself.
  
- Change required is trivial, in debian/rules:
+ [Impact] libxml2-dev is not M-A co-installable
+ 
+ [Development Fix] libxml2 version 2.7.8.dfsg-9 in Debian Sid
+ 
+ [Stable Fxi] Change required is trivial, in debian/rules:
  
  -	sed -i -e 's,/usr/lib/$(DEB_HOST_MULTIARCH),/usr/lib,' debian/libxml2-dev/usr/bin/xml2-config
  +	sed -i -e 's,/lib/$(DEB_HOST_MULTIARCH),/lib,' debian/libxml2-dev/usr/bin/xml2-config
+ 
+ [Test Case] Enable M-A in testing environment (amd64 for instance), and
+ try to install both libxml2-dev:i386 and libxml2-dev:amd64 which were
+ newly built with the mentioned patch. If the action failed with
+ something like './usr/bin/xml2-config' is different from the same file
+ on the system, then the bug was not fixed.
+ 
+ [Regression Potential] xml2-config reports the libdir is /usr/lib, while
+ the actual ones are /usr/lib/<triplets>. This might break applications
+ whose build system can't find libraries correctly in the previous path
+ but relies on xml2-config's output. I recommend to use pkg-config
+ instead of this script.

Bug description:
  [Background] In the M-A implementation of version
  2.7.8.dfsg-5.1ubuntu1, /usr/bin/xml2-config still contains M-A
  tripples, which is troublesome when the package libxml2-dev is marked
  as M-A: same. The problem is caused by the sed call in debian/rules
  says "usr/lib/<tripple>", while it wasn't like that in xml2-config
  script itself.

  [Impact] libxml2-dev is not M-A co-installable

  [Development Fix] libxml2 version 2.7.8.dfsg-9 in Debian Sid

  [Stable Fxi] Change required is trivial, in debian/rules:

  -	sed -i -e 's,/usr/lib/$(DEB_HOST_MULTIARCH),/usr/lib,' debian/libxml2-dev/usr/bin/xml2-config
  +	sed -i -e 's,/lib/$(DEB_HOST_MULTIARCH),/lib,' debian/libxml2-dev/usr/bin/xml2-config

  [Test Case] Enable M-A in testing environment (amd64 for instance),
  and try to install both libxml2-dev:i386 and libxml2-dev:amd64 which
  were newly built with the mentioned patch. If the action failed with
  something like './usr/bin/xml2-config' is different from the same file
