------- Comment #9 from rguenth at gcc dot gnu dot org  2009-11-02 16:29 -------
Ok, so I reproduced it and used make -d install this time.  The issue is

Reading makefile `Makefile'...
Reading makefile `.deps/lto-plugin.Plo' (search path) (no ~ expansion)...
Updating makefiles....
 Considering target file `.deps/lto-plugin.Plo'.
  Looking for an implicit rule for `.deps/lto-plugin.Plo'.
...
 No need to remake target `Makefile'.
Updating goal targets....
Considering target file `install'.
 File `install' does not exist.
  Considering target file `install-am'.
   File `install-am' does not exist.
    Considering target file `all-am'.
     File `all-am' does not exist.
      Pruning file `Makefile'.
      Considering target file `liblto_plugin.la'.
        Considering target file `lto-plugin.lo'.
...
          Must remake target
`/usr/src/packages/BUILD/gcc-4.5.0-20091029/obj-x86_64-suse-linux/./prev-gcc/include/stdbool.h'.
          Successfully remade target file
`/usr/src/packages/BUILD/gcc-4.5.0-20091029/obj-x86_64-suse-linux/./prev-gcc/include/stdbool.h'.
...
         Finished prerequisites of target file `lto-plugin.lo'.
         Prerequisite `../../lto-plugin/lto-plugin.c' is older than target
`lto-plugin.lo'.
...
         Prerequisite
`/usr/src/packages/BUILD/gcc-4.5.0-20091029/obj-x86_64-suse-linux/./prev-gcc/include/stddef.h'
of target `lto-plugin.lo' does not exist.
...
         Prerequisite
`/usr/src/packages/BUILD/gcc-4.5.0-20091029/obj-x86_64-suse-linux/./prev-gcc/include/stdarg.h'
of target `lto-plugin.lo' does not exist.
...
         Prerequisite
`/usr/src/packages/BUILD/gcc-4.5.0-20091029/obj-x86_64-suse-linux/./prev-gcc/include/stdint.h'
of target `lto-plugin.lo' does not exist.
...
         Prerequisite
`/usr/src/packages/BUILD/gcc-4.5.0-20091029/obj-x86_64-suse-linux/./prev-gcc/include/stdbool.h'
of target `lto-plugin.lo' does not exist.
...
        Must remake target `lto-plugin.lo'.


which is probably caused by either

#include <stdbool.h>

or

#include <inttypes.h>
