Add linux-oe-g++ platform

* This qmake.conf unlike other platforms reads most variables from
  shell environment, because it's easier for qt recipes to export
  *FLAGS or CC specific for given recipe

* configure: add getQEvalMakeConf and getXQEvalMakeConf
  Allow expansion of $(...) references from qmake.conf to generate
  qmake environment from shell environment as exported by qmake5_base

* OE_QMAKE_CXX in order to allow compiler version check to succeed
  which allows WebKit to be enabled.

* Other variables in order to let config.tests to use our -platform
  settings

* Add setBootstrapEvalVariable to bootstrap qmake with our environment
  too, this allows us to use -platform linux-oe-g++ also for native
  recipe

* disable gdb_dwarf_index
  * qmake is trying to call native gdb and we don't depend on gdb-native
    (or even provide gdb-native)
  * fixes errors like this:
    /bin/sh: gdb: command not found
    /bin/sh: line 0: test: -gt: unary operator expected
    which are not fatal, but still misleading in do_configure output

qlibraryinfo: allow to set qt.conf from the outside using the environment

Allow to set a qt.conf from the outside using the environment. This allows
to inject new prefixes and other paths into qmake. This is needed when using
the same qmake binary to build qt/x11 and qt/embedded

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].

qt_module: Fix pkgconfig replacement

* 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

qtbase: allow build of examples

    do not actually build examples in production builds

    -developer-build enables an actual build of examples, based on the
    assumption that developers want to test it (it can be still disabled
    with -nomake examples). regular users otoh want only the examples
    sources installed.
