[xml/sgml-pkgs] Bug#952768: libxslt1-dev amd64 and i386 no longer multi-arch coinstallable

[Christian Klein]

Package: libxslt1-dev
Version: 1.1.34-3
Severity: normal

Starting with libxslt 1.1.34-2 and later, the -dev packages for amd64 and i386
can no longer be installed together.

Unpacking libxslt1-dev:i386 (1.1.34-3) ...
dpkg: error processing archive
/var/cache/apt/archives/libxslt1-dev_1.1.34-3_i386.deb (--unpack):
 trying to overwrite shared '/usr/bin/xslt-config', which is different from
other instances of package libxslt1-dev:i386
dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)
Errors were encountered while processing:
 /var/cache/apt/archives/libxslt1-dev_1.1.34-3_i386.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

The problem is caused by the re-inclusion of xslt-config.
Unlike the version that shipped until 1.1.32-2.2, the new file contains the
libdir, which is different for both architectures.
The old xslt-config did not contain a libdir and was the same for both
architectures.
