This patch adds gnulib-longdouble-redirect.patch, which is a subset of gnulib commit 776af40e09b476a41073131a90022572f448c189. This patch must be applied to the copy of gnulib which is vendored within a few packages, when compiling for platforms that use longdouble-redirection (a glibc-specific feature). Without it, compile failures mentioning "__LDBL_REDIR1_DECL" will occur. Currently there are two packages which need this patch to their vendored gnulib: gettext and gnused. Both projects have merged a fixed version of gnulib but have not yet made a release with the fix. We can drop this patch as soon as both of those projects are version-bumped.
