[patch] allocate name of anonymous objfiles properly

[David Carlton]

In my earlier patch to make sure that anonymous objfiles have a name,
I neglected to ensure that the name is allocated properly.  This can
cause problems if an objfile is unloaded and loaded again, because in
that case somebody will try to free the name, which you can't do if
the name is a constant string.  Oops.

This patch fixes that; I've tested it with GCC 3.2, DWARF 2,
i686-pc-linux-gnu.  It seems obvious; I'll commit it on Friday unless
somebody objects.

	* objfiles.c (allocate_objfile): For anonymous objfiles, allocate
	the name with mstrsave.
