Fix external toolchain build
This patch is a new version of a patch already sent several times on the mailing-list, committed and reverted a few times by Daniel Laird, due to several imperfections. This version is a new try at finding a solution that works for everybody. Hopefully it'll work :-) The original problem is that external toolchain builds failed because packages couldn't find their dependent libraries at configure time and could not be linked with them. To fix these two problems, two things are added: * The TARGET_LDFLAGS variable was exposed as LDFLAGS at ./configure time thanks to TARGET_CONFIGURE_OPTS. The TARGET_LDFLAGS variable contains -L options with the path in the STAGING_DIR for the libraries. It allows ./configure scripts to properly compile the small test programs testing whether a dependency is properly installed. * The TARGET_CFLAGS contains a new -Wl,--rpath-link option for both $(STAGING_DIR)/lib and $(STAGING_DIR)/usr/lib. It allows library depending on other libraries to link properly. The TARGET_CFLAGS is exposed as CFLAGS in TARGET_CONFIGURE_OPTS. This new version fixes a problem encountered by hartleys <hartleys@visionengravers.com> when building the kernel. The problem was that the -Wl,--rpath-link options were added to LDFLAGS, while there are options for the C compiler, not the ld linker. Moving them to CFLAGS seems to fix the issue.
