[Buildroot] [git commit] libtool: Apply upstream patch to set correct linkage on MIPS64

commit: http://git.buildroot.net/buildroot/commit/?id=4268d3967e2d691c151d6b5629e4051deb077b9a
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

This libtool change ensures that ld uses the right machine emulation file,
which will allow to fix several MIPS64 n64 link failures, such as the one
currently visible on the libiscsi package.  Packages affected by this
problem will have to use <pkg>_AUTORECONF = YES to benefit from this libtool
fix, until they are fixed upstream.
