Patch for fix libtool when install does a relink. (repost)

[Mo DeJong]

Hi all.

There is a small bug in libtool that only seems to show up
when running an install command like so:

libtool --mode=install install -c  subdir/libdemo.la /tmp/demo/libdemo.la

This only happens when the relink_command inside the .la file
does a cd to some other directory. After the relink_command
is run the rest of the install will puke out. This also
only seems to happen when one .la file depends on another
.la file. Here is some example error output:

libtool: install: warning: relinking `subdir/libdemo.la'
cd /home/mo/project/build/libtool_full_bug/subdir; /bin/sh ../libtool 
--mode=relink gcc -o libdemo.la -rpath 
/home/mo/project/build/libtool_full_bug/install/lib demo.lo -L. -lbug
gcc -shared  demo.lo  -Wl,--rpath 
-Wl,/home/mo/project/build/libtool_full_bug/install/lib  
-L/home/mo/project/build/libtool_full_bug/subdir 
-L/home/mo/project/build/libtool_full_bug/install/lib -lbug   -Wl,-soname 
-Wl,libdemo.so.0 -o .libs/libdemo.so.0.0.0
install -c subdir/.libs/libdemo.so.0.0.0T 
/home/mo/project/build/libtool_full_bug/install/lib/libdemo.so.0.0.0
install: subdir/.libs/libdemo.so.0.0.0T: No such file or directory


The relink command in the .la file might look like so:

relink_command="cd /usr/build/foo ; /bin/sh /usr/foo/libtool ..."

That makes the next install fail since the CWD will then be /usr/build/foo.

Here is a patch that fixes the problem.

        * ltmain.in: Place parens around a generated relink_command
        so it is run is a subshell. This avoids an install error
        where libtool ended up in the wrong directory after
        relinking a .la file.
