[PATCH] Use AC_PROG_SED and respect its result

[Yaakov (Cygwin/X)]

From: Yaakov Selkowitz <yselkowitz at users.sourceforge.net>

AC_PROG_SED sets SED as the path to a fully-functional 'sed' (which may
also be called 'gsed' if GNU sed is installed alongside a proprietary
version).

This is a follow up to commit 9be4157391edf0c5fc4ee36adfb1eb1c3bdb8e3b.
