[oe] qt-4.6.3

Hi,

For some reason, my build of qt4-4.6.3 fails with undefined references
to libiconv (see below). This is indeed the case because qt-core is not
linked against it. More specifically, in src/corelib/codecs/codecs.pri
the -liconv is assigned to the variable LIBS_PRIVATE. This means that
libiconv is not part of the public interface of qt-core and that the
-liconv is only used when building static libraries, not dynamic ones.
However, the link flag, -Wl,--no-undefined, requires that there are no
undefined symbols when final linking. Manually removing the
-Wl,--no-undefined from the generated Makefile in src/corelib makes the
problem go away.
I suppose the real way to correct this in the bitbake file is overriding
the LDFLAGS, but is there some way to remove part of the LDFLAGS?

Regards,

Jan
