Sync pkg-config 0.28-1 (main) from Debian unstable (main)

Please sync pkg-config 0.28-1 (main) from Debian unstable (main)

Explanation of the Ubuntu delta and why it can be dropped:
  * debian/rules: Set GCC and PKG_CONFIG for cross builds.
  * Apply upstream patch from Michał Sawicz to allow ~ through unescaped.
  * Trivially convert to 3.0 (quilt) and dh-autoreconf to help apply the
    above patch.
  * debian/pkg-config-crosswrapper: fix to use PKG_CONFIG_PATH pointed to
    both the multiarch path and the traditional cross-build path, instead of
    just settting PKG_CONFIG_LIBDIR to the traditional cross-compiler path,
    so that we can use this successfully in a multiarch environment.
    Closes: #631275.
  * debian/control: mark pkg-config Multi-Arch: foreign; it provides an
    executable interface which points to architecture-dependent paths, but
    those paths only need to be overridden in a cross-build environment, in
    which case it's the responsibility of the cross-toolchain packages to
    provide the appropriate glue.
This entire delta is unnecessary now. All of the changes are in Debian/the new upstream release.

Changelog entries since current utopic version 0.26-1ubuntu4:

pkg-config (0.28-1) unstable; urgency=medium

  * New upstream release. (Closes: #699476, #744031)
    - Updated man page with fewer errors. (Closes: #661838)
  * Fix test running with newer automake.
  * Drop popt stuff from debian/rules, upstream no longer ships popt.

pkg-config (0.26-1+autoconf) unreleased; urgency=medium

  * Non-maintainer upload.
  * Update config.{sub,guess} for new arches (with dh-autoreconf) (Closes: #742665)
  * Add Multiarch metadata (M-A: foreign), so this package can
    satisfy cross- build-dependencies. The cross-build environment is
    responsible for providing the $triplet-pkg-config symlink to
    pkg-config-crosswrapper. (Closes: #726598)
  * Update crosswrapper script to search multiarch paths, traditional
    cross-compilation paths, arch-independent paths, and /usr/local counterparts.
    Thanks to Simon McVittie, Steve Langasek, Vincent Danjean, Wookey
    (Closes: #642292, #650298, #631275)
  * Make pkg-config itself cross-buildable. (Closes: #716918)
