libtool 1.4 leaves .o.lock file lying around

[Bruno Haible]

Hi,

On IRIX 6.5, libtool 1.4 leaves a .o.lock file on the disk. I have to
remove it later during "make clean".

To reproduce,
- take libiconv-1.7 from ftp://ftp.gnu.org/pub/gnu/libiconv/
- configure and compile:
   $ CC="cc -O" ./configure
   $ make
   $ ls -li libtool libcharset/libtool libcharset/lib/localcharset.o.lock
272318 -rwxr-xr-x    2 haible   talk      146616 Jun 29 20:18 
libcharset/lib/localcharset.o.lock
272318 -rwxr-xr-x    2 haible   talk      146616 Jun 29 20:18 libcharset/libtool
 99512 -rwxr-xr-x    1 haible   talk      146628 Jun 29 20:17 libtool

I think libtool ought to remove its lock files once the compilation is
done, because it's only a means to make parallel builds work.

Bruno

  be some backslashification problems when reading/writing sed expressions
  from the autoconf cache.
