In fact, after a lot of tests I found quite the contrary, but it can also be a 
bug. I ended uninstalling the autotools from Debian, in case they had left any 
older file from previous versions and compiling autoconf, automake and libtool 
from the git repositories. The behavior was the same, after the "autoreconf -
vfi", no ltmain.sh was copied into the directory.

I followed the strace of libtoolize on two different located source trees and 
found that this program looks for install.sh or install-sh in the parent and 
the grandparent directory. Here are two straces, one from a source tree with a 
install-sh in its grandparent directory and another which does not:

stat("./install-sh", 0x7fffa4d70780)    = -1 ENOENT (No such file or 
directory)
stat("./install.sh", 0x7fffa4d70750)    = -1 ENOENT (No such file or 
directory)
stat("../install-sh", 0x7fffa4d70780)   = -1 ENOENT (No such file or 
directory)
stat("../install.sh", 0x7fffa4d70750)   = -1 ENOENT (No such file or 
directory)
stat("../../install-sh", {st_mode=S_IFREG|0755, st_size=13663, ...}) = 0

stat("./install-sh", 0x7fff04083cf0)    = -1 ENOENT (No such file or

stat("./install.sh", 0x7fff04083cc0)    = -1 ENOENT (No such file or 
directory)
stat("../install-sh", 0x7fff04083cf0)   = -1 ENOENT (No such file or 
directory)
stat("../install.sh", 0x7fff04083cc0)   = -1 ENOENT (No such file or 
directory)
stat("../../install-sh", 0x7fff04083cf0) = -1 ENOENT (No such file or 
directory)
stat("../../install.sh", 0x7fff04083cc0) = -1 ENOENT (No such file or 
directory)

=========[without]================

If those files are not found, everything works well. If one of them is, then 
no ltmain.sh is copied and the building system is messed up.

I don't know Autotools internals, so I don't know if I should file a bug or if 
it is my mistake...
