Title:
  PKG_CONFIG_PATH in pkg-config-crosswrapper

Status in pkg-config package in Ubuntu:
  Confirmed

Bug description:
  I was wondering, why my Jenkins build failed after upgrade to Ubutnu
  14.04, now I see that in pkg-config-crosswrapper my variable
  PKG_CONFIG_PATH is brutally overwritten.

  How am I supposed to set a PKG_CONFIG_PATH in a cross-compile
  environment?

  IMHO: PKG_CONFIG_PATH must not be overwritten in pkg-config-
  crosswrapper.

  I now manually edited /usr/share/pkg-config-crosswrapper (added ":${PKG_CONFIG_PATH}") to become:
  {{{
  #! /bin/sh
  # pkg-config wrapper for cross-building
  # Sets pkg-config search path to target arch path only.

  triplet=`basename $0 | sed -e 's:-pkg-config::'`
  PKG_CONFIG_PATH=/usr/lib/${triplet}/pkgconfig:/usr/${triplet}/lib/pkgconfig:${PKG_CONFIG_PATH} pkg-config $@
  }}}

  My jenkins build script is:

  {{{ (added ":${PKG_CONFIG_PATH}")
  PKG_CONFIG_PATH=${HOME}/qt-${MINGW}/lib/pkgconfig \
    CPPFLAGS="-I${WORKSPACE}/usr/include" \
    LDFLAGS="-L${WORKSPACE}/usr/lib" \
    ./configure --prefix=${WORKSPACE}/usr --host=${MINGW}
  make all install
  }}}

  
  Manually changing a package-provided file is a dirty hack. So do you change your code or do I have another/better way for providing my additional path?
