Add -rpath option for host package compilation
In c1b6242fdcf2cff7ebf09fec4cc1be58963e8427, we added
$(HOST_DIR)/usr/lib to LD_LIBRARY_PATH when building target packages,
because the build of target packages sometimes require host tools
installed in $(HOST_DIR)/usr/bin which themselves require host
libaries installed in $(HOST_DIR)/usr/lib.
Unfortunately, this solution didn't work, as libtool then tried to
link target binaries against host libraries. So $(HOST_DIR)/usr/lib
got removed from LD_LIBRARY_PATH in
0d1830b07db4ebfd14e77a258de6fb391e57e960.
However, this meant that we went back to the previous situation, in
which host tools used during compilation of target components might
require host libraries. An example :
make[2]: Entering directory `/home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/build/xfont_font-adobe-100dpi-1.0.1'
/home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/host/usr/bin/mkfontdir /home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/target/usr/share/fonts/X11/100dpi
/home/test/buildroot/output.ctng-arm-eglibc-2010-05-04-12-41-00/host/usr/bin/mkfontscale: error while loading shared libraries: libfontenc.so.1: cannot open shared object file: No such file or directory
Therefore, we try another solution: make sure that host binaries are
linked with an -rpath option, so that $(HOST_DIR)/usr/lib doesn't need
to be in LD_LIBRARY_PATH for them to find their libraries.
