2.26-0ubuntu1 breaks compliation of several KDE sources

[Rik Mills]

gblic 2.26-0ubuntu1 which removed xlocale.h: breaks compliation of several KDE sources, but libxslt still requires that header.

Including so far, but maybe not limited to is autotests:

kde4libs
kio
kopete

with the error

In file included from /usr/include/libxslt/xsltInternals.h:24:0,
                 from /usr/include/libxslt/xsltutils.h:23,
                 from /tmp/autopkgtest.U99BLh/build.W2l/kde4libs-4.14.34/kdoctools/kio_help.cpp:61:
/usr/include/libxslt/xsltlocale.h:20:10: fatal error: xlocale.h: No such file or directory
 #include <xlocale.h>
          ^~~~~~~~~~~
compilation terminated.

Confirmed also in kio package rebuild in our staging ppa

Trying to build without kio for example, without libxslt results in a build fail with:

-- The following REQUIRED packages have not been found:

 * LibXslt, <http://xmlsoft.org/XSLT>
   Required by the KDE help system to process DocBook XML

CMake Error at /usr/share/cmake-3.9/Modules/FeatureSummary.cmake:459 (message):
  feature_summary() Error: REQUIRED package(s) are missing, aborting CMake
  run.

Even in the latest libxslt git revision,

https://git.gnome.org/browse/libxslt/tree/libxslt/xsltlocale.h

#include <xlocale.h>

is required.

[Dimitri John Ledkov (xnox)]

xlocale.h is no longer shipped or required; use locale.h instead.

[Launchpad Janitor (janitor)]

This bug was fixed in the package libxslt - 1.1.29-2.1ubuntu1

---------------
libxslt (1.1.29-2.1ubuntu1) artful; urgency=medium

  * Add rename build-dependency.
  * Stop unconditionally including xlocale.h header in xsltlocale.h as it
    is no longer shipped by glibc2.26. Ideally existing autoconf checks
    should be used to generate xsltlocale.h with or without xlocale.h
    include. LP: #1715599
