./configure fails due to obselete usage of 'find -perm' in aclocal.m4
- /configure produces error message when building on current Fedora (20). According to find ver 4.5.11 the usage '-perm +XXX' has been deprecated since 2005 (use '-perm \XXX' instead). The message '/usr/bin/find: invalid mode '+111' ' is seen several times as a result.
Whether this has any material impact I am not qualified to judge. I am actually trying to build HaLVM (from Galois) and first noticed the issue in their fork of GHC. However, this behaviour is also present in git HEAD (commit d7867810). Making the obvious one line change in aclocal.m4 resolves the issue, and produces a clean build, for me at least. Patch attached
