Subject: qt4: fix generated sdk
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- qt4-tools-nativesdk : actually the qmake binary which gets installed
comes from the native recipe. This patch fix this problem by launching
configure twice : once to compile qmake using the right toolchain for
nativesdk, and a second time using the native qmake to compile all the
other tools for the nativesdk. Then we install the right qmake.

- mkspec : the link actually created in qt4-tools-nativesdk's
do_install point to nowhere so remove it and generate the link in
meta-toolchain-qte as it's the only place where we have all the variable
to create it.

- toolchain_create_sdk_env_script_append : we need to add OE_QMAKE_CFLAGS,
OE_QMAKE_CXXFLAGS and OE_QMAKE_LDFLAGS else the sdk won't find these
variables that are inserted by qmake in the Makefiles.

- with this patch, oe-core generates a working meta-toolchain-qte which
can compile a small example and is properly recognized by qtcreator (this
brings oe-core's meta-toolchain-qte to oe-dev's functional state).
