			== Testing prelink/cross-prelink on Ubuntu ==

			On recent Ubuntu versions, the default gcc passes -Wl,--as-needed to the linker by default (see [https://wiki.ubuntu.com/ToolChain/CompilerFlags#A-Wl.2C--as-needed here] for more info). This will cause some prelink/cross-prelink tests to [http://sourceware.org/ml/prelink/2013-q2/msg00002.html fail]. This can be worked around by passing overrides in CC and CXX to make check:
			<nowiki>
			$ make check CC='gcc -Wl,--no-as-needed' CXX='g++ -Wl,--no-as-needed'</nowiki>

			On recent Ubuntu versions, the libraries are layed out according to the [https://help.ubuntu.com/community/MultiArch multiarch spec]. This causes most cross-prelink tests to fail. This can be worked around by passing a library path to prelink-rtld:
			<nowiki>
			$ make check LDD="../src/rtld/prelink-rtld --library-path=/lib/x86_64-linux-gnu:/usr/lib/x86_64-linux-gnu"</nowiki>

	The cross prelink patches began at MontaVista around 2003 in order to work around this limitation. The original patches added the ability to emulate a runtime linker, as well as enabled a sysroot option. Over time, this work was continued by MontaVista, Wind River and ~~Code Sourcery~~. Unfortunately, while all of the patches had been made public in one fashion or another, there was no central location that gathered and offered to manage these changes. Starting with the Yocto Project we have decided to put together these patches and make them available as a single unit, with a clear upstream that will happily accept patches.
