New Recipe: lib4ti2 1.6.9

[fingolfin]

This contains some nasty workarounds for issues with libstdc++.la -- I wonder if these hint at an issue with the build environment? Or perhaps I am doing something stupid? (perhaps @benlorenz has an idea -- but don't feel compelled to look, or waste time on this).

There are a few issues building everything for all platforms, so I may have to disable some. But I thought I should submit this now, even though it is not 100% ready, in the hopes that somebody has feedback on the libstdc++.la problems, and also so that I can show this more easily to people who might be interested in using this (e.g. @mohamed-barakat). And finally perhaps there are other things I should be doing differently here, then it'd be good to hear about it sooner rather than later :-).

For the libtool files you can try rm -f ${prefix}/lib/libgmpxx.la instead (always in lib and not $libdir), the file is not really necessary.

Maybe the libtool file should be deleted or adjusted in the gmp package?

Just remove all libtool archives, they are often wrong:

Yggdrasil/G/gperftools/build_tarballs.jl

Lines 17 to 20 in faf8816

	# Remove misleading libtool files
	rm -f ${prefix}/lib/*.la
	rm -f /opt/${target}/${target}/lib*/*.la
	rm -f /opt/${MACHTYPE}/${MACHTYPE}/lib*/*.la

. We should get rid of them in the RootFS: JuliaPackaging/BinaryBuilder.jl#689

Thank you all for the very helpful comments!
