libtoolize /ltmain.sh bug

[Ralf Wildenhues]

Hello,

In an empty directory this happens:

$ libtoolize --copy --ltdl
touch: cannot touch `/ltmain.sh': Permission denied
libtoolize: can not copy `/home/ralf/local/share/libtool/config/ltmain.sh' to 
`/'
libtoolize: copying file `libltdl/config/compile'
libtoolize: copying file `libltdl/config/config.guess'
libtoolize: copying file `libltdl/config/config.sub'
libtoolize: copying file `libltdl/config/depcomp'
libtoolize: copying file `libltdl/config/install-sh'
libtoolize: copying file `libltdl/config/missing'
libtoolize: copying file `libltdl/config/ltmain.sh'
libtoolize: putting macros in `libltdl/m4'.
[...]

First, the toplevel directory isn't even a package, so it should not get
an ltmain.sh file at all (it does, however, unlike what the bogus error
suggests).  Second, there is a '.' missing before /ltmain.sh.

I think this is a regression in the recent flurry of libtoolize.m4sh
changes, IIRC this worked well a while ago.

Cheers,
Ralf
