Add -external-hostbindir option

* when cross-compiling it's sometimes useful to use existing tools from machine
  (or in OpenEmbedded built with separate native recipe) when building for target

* this way we can skip bootstraping tools we already have

* qt_functions: temporary remove isEmpty check
* now we assume that every build will provide QT_EXTERNAL_HOST_BINS value
* isEmpty works correctly only with qmake variables (e.g. $$FOO -
  isEmpty(FOO)), but doesn't work with system properties like $$[FOO].

* cmake: Use OE_QMAKE_PATH_EXTERNAL_HOST_BINS to determine path to host binaries

  again a bit OE specific
qt_module: Fix pkgconfig and libtool replacements

* in situation like this:
  QT_SYSROOT:/OE/oe-core/tmp-eglibc/sysroots/qemuarm
  QT_INSTALL_LIBS:/OE/oe-core/tmp-eglibc/sysroots/qemuarm/usr/lib
  QT_INSTALL_LIBS/raw:/usr/lib
  QT_INSTALL_LIBS/get:/OE/oe-core/tmp-eglibc/work/armv5te-oe-linux-gnueabi/qtbase/5.0.0-r0.0/build/lib

  I don't want the replacement like this:
  sed
    -e "s,/OE/oe-core/tmp-eglibc/work/armv5te-oe-linux-gnueabi/qtbase/5.0.0-r0.0/build/include,/usr/include/qt5,g"
    -e "s,/OE/oe-core/tmp-eglibc/work/armv5te-oe-linux-gnueabi/qtbase/5.0.0-r0.0/build/lib,/usr/lib,g"
    "../../lib/pkgconfig/Qt5Core.pc"
    >"/OE/oe-core/tmp-eglibc/work/armv5te-oe-linux-gnueabi/qtbase/5.0.0-r0.0/image/OE/oe-core/tmp-eglibc/sysroots/qemuarm/usr/lib/pkgconfig/Qt5Core.pc"
  because that way I'll end with -L/usr/lib in .pc file which is
  cross-compile unfriendly, keeping ${libdir}/${includedir} works better
  in my case

* qt_module: Fix paths in .prl files
* qmake does not prefix them with QT_SYSROOT when using them
  so e.g. when building qtdeclarative we get -L/usr/lib to LINKAGE
  variable, which is unsafe for cross-compilation
* writting QT_SYSROOT in .prl files is dangerous for sstate when
  builds are in different directories, so we need
  SSTATE_SCAN_FILES += "*.pri *.prl"
  to make them relocateble

* fix paths in packageconfig files
  This reverts parts of:

  enable path replacement in installed prl files on all platforms

* to debug this, rebuild qtbase and read build/src/corelib/Makefile
* this is example of broken install_target rule (added line feeds):
  -$(SED) -e s,/OE/5.3.1-r0/build/lib,/usr/lib,g
          -e 's,/OE/5.3.1-r0/build/include,$$\{includedir},g'

     "../../lib/pkgconfig/Qt5Core.pc"
     >"$(INSTALL_ROOT)/usr/lib/pkgconfig/Qt5Core.pc"
  change .prf files, create copy of WORKDIR, re-excecute only
  do_configure task and compare generated Makefile, repeat until
  replace in generated Makefile works ok, then refresh patch and
  try complete rebuild for qtbase
* if everything is ok, then try:
  image $ grep -R "\-L/usr" .
  image $ grep -R "\-I/usr" .
  and it should return only few cases of
  qmake.conf:QMAKE_LFLAGS_THREAD     = -L/usr/lib/threads
  for aix* platformas
