I've seen this in a few different configurations, so I didn't think
that you needed anything special.  But anyway, here is one possible
defconfig:

    BR2_arm=y
    BR2_cortex_a8=y
    BR2_ARM_FPU_NEON=y
    BR2_ENABLE_DEBUG=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_PACKAGE_GSTREAMER=y
    BR2_PACKAGE_GST_FFMPEG=y
    # BR2_TARGET_ROOTFS_TAR is not set

Look at the very end of the configure step, just before the build step:

    License: GPL version 2 or later
    Creating config.mak and config.h...

    WARNING: xxxx/output/host/usr/bin/arm-none-linux-gnueabi-pkg-config
not found, library detection may fail.
    configure: WARNING: unrecognized options: --disable-doc,
--disable-docs, --disable-documentation, --with-xmlto, --with-fop,
--enable-ipv6
    configure: *** Orc acceleration disabled.  Requires Orc >= 0.4.6,
which was not found.  Slower code paths will be used.
