make sdist fails with repeated /bin/sh[1]: lndir: not found [No such file or directory]

It appears that source for lndir was intentionally included in utils and customized to handle .git directories: http://git.haskell.org/ghc.git/blobdiff/c629bd1539b1865cc28ce053234595e7aeb8a5c0..8023014ecf192381ffba4b60a3dd21630e5c1d18:/utils/lndir/lndir.c

This ignoring of .git directories has been in the upstream lndir.c since 2009: http://cgit.freedesktop.org/xorg/util/lndir/tree/lndir.c

However, lndir is not installed by default (on Ubuntu or SmartOS) and is not listed in the tools required to build: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Tools

It does not appear to be built during the sync, boot, or make steps of a GHC build.

Here is an excerpt:

/bin/sh[1]: lndir: not found [No such file or directory]
