[Buildroot] [PATCH] qt5: install headers into /usr/include/qt5

[Fatih Aşıcı]

There are places in Qt's source where headers included with the name of
the module subdirectory (e.g. #include <QtCore/QHash>). Therefore, the
build system passes the top header directory to the compiler; but this
results in a error when building host tools since sysroot/usr/include
directory includes architecture specific system headers.

In order to prevent this, install all Qt headers into a subdirectory in
/usr/include.

Fixes: http://autobuild.buildroot.net/results/4f1/4f16c0b38bdd6e40efcc781c12fae81c0bfabb72/
