[OE-core] [PATCH 1/1] qt-mobility: remove /usr/lib from ld rpath-link option

[rongqing.li at windriver.com]

From: "Roy.Li" <rongqing.li at windriver.com>

Remove /usr/lib from ld rpath-link option to fix the below build error:

       bitbake_build/tmp/sysroots/x86-kvm-guest/usr/lib/libpng16.so.16:
        undefined reference to `inflateReset2 at ZLIB_1.2.3.4'

since sysroot seems not work for rpath-link, and "rpath-link,/usr/lib" makes
ld to search host libraries for target libraries, once host has different
version zlib, the error will happen.

qmake uses QT_MOBILITY_LIB to generate "rpath-link,/usr/lib" when do_configure
but we can not add sysroot into QT_MOBILITY_LIB, since QT_MOBILITY_LIB is dir
which libraries will be installed to, so I remove this dir from rpath-link
before do_compile
