[Buildroot] [PATCH v2] libtool: Apply upstream patch to set correct linkage on

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.
