Subject: [PATCH] * autogen.sh: Fix for Solaris 10.

o Replace `test -e` by `test -d` (directory) and `-h`
  (symlink), because pre-POSIX /bin/sh of Solaris 10
  does not support `test -e`.
o Replace the combination of `head` and `sed ...` by
  single sed command `sed -n 1...p`.  GNU libtoolize
  with Solaris 10 /bin/sh complains "Broken Pipe" for
  the closure of stdout by `head`.  Let `sed` receive
  all stdout and discard.
