Problem reproducible with the following defconfig:

BR2_x86_64=y
BR2_x86_corei7=y
BR2_COMPILER_PARANOID_UNSAFE_PATH=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/x86_64-ctng_locales-linux-gnu.tar.xz"
BR2_TOOLCHAIN_EXTERNAL_CUSTOM_PREFIX="x86_64-ctng_locales-linux-gnu"
BR2_TOOLCHAIN_EXTERNAL_GCC_4_8=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_3_9=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM_GLIBC=y
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_PACKAGE_QT=y
BR2_PACKAGE_QT_LICENSE_APPROVED=y
# BR2_PACKAGE_QT_XML is not set
# BR2_PACKAGE_QT_SCRIPT is not set
BR2_PACKAGE_LIBV4L=y
BR2_PACKAGE_LIBV4L_UTILS=y

with buildroot up to commit 912538634a778452196c49726bb0770885280adc, but only
if libv4l is build after qt (something like
    ifeq ($(BR2_PACKAGE_QT),y)
    LIBV4L_DEPENDENCIES += qt
    endif
is missing from libv4l.mk).

Reverting commit d7f6d320b64ae582d17362dae971288c993736dc 'pkgconf: bump to version 0.9.12' fixes the problem...
