Infrastructure: update the pkg-infrastructure to more recent versions

These updates enable builds in '/usr/src/'
glibc: remove gcc-intermediate dependency

A two phase gcc build is sufficient
toolchain: trigger the CMake toolchain file

This toolchain file is used by multiple packages
Infrastructure: set CMAKE_MAKE_PROGRAM

This variable should be defined
qt5: support the more recent infrastructure

'/usr/src/' builds should be supported like the more recent versions of this file do
uclibc: remove gcc-intermediate and toolchain dependency
host-gcc-initial: libc will provide SSP support

This fixes the uClibc build
