[kaffe] chmod +x libltdl/install-sh

[Ito Kazumitsu]

Hi,

I needed to chmod +x libltdl/install-sh because "make install" on
FreeBSD 5.3-RELEASE tries to execute it instead of "mkdir -p".

But why should libltdl/install-sh be executed when "mkdir -p"
can be used?

Because the behaviour of mkdir of FreeBSD has changed and
configure cannot detect it. 

"mkdir -p --version ." shows:

On FreeBSD 5.2.1-RELEASE: 

$ mkdir -p --version .
$ 

On FreeBSD 5.3-RELEASE:

$ mkdir -p --version .
mkdir: illegal option -- -
usage: mkdir [-pv] [-m mode] directory ...
$
