   Wrapper for pkg-config

      - In order to make proper use of pkg-config so that configure is able to

        find all dependencies you should create a wrapper script for pkg-config;

        file /opt/arm-linux-androideabi-4.4.3/bin/arm-linux-androideabi-pkg-config:

        #!/bin/sh

        SYSROOT=$(dirname ${0%/*})/sysroot

        export PKG_CONFIG_DIR=

        export PKG_CONFIG_LIBDIR=${SYSROOT}/usr/local/lib/pkgconfig:${SYSROOT}/usr/share/pkgconfig

        export PKG_CONFIG_SYSROOT_DIR=${SYSROOT}

        exec pkg-config "$@"

        also create a copy or symlink with name arm-unknown-linux-androideabi-pkg-config.
