Calling ld directly yields:

$ /home/georg/install/gcc-4.7/lib/gcc/avr/4.7.0/../../../../avr/bin/ld --help |
grep -i plug
  -plugin PLUGIN              Load named plugin
  -plugin-opt ARG             Send arg to last-loaded plugin
/home/georg/install/gcc-4.7/lib/gcc/avr/4.7.0/../../../../avr/bin/ld: supported
targets: elf32-avr elf32-little elf32-big plugin srec symbolsrec verilog tekhex
binary ihex

So there is nothing wrong with the install.

$ ll /home/georg/install/gcc-4.7/libexec/gcc/avr/4.7.0/liblto_plugin.so
/home/georg/install/gcc-4.7/libexec/gcc/avr/4.7.0/liblto_plugin.so ->

$ ls -al /home/georg/install/gcc-4.7/libexec/gcc/avr/4.7.0/liblto*
 /home/georg/install/gcc-4.7/libexec/gcc/avr/4.7.0/liblto_plugin.so ->
 /home/georg/install/gcc-4.7/libexec/gcc/avr/4.7.0/liblto_plugin.so.0 ->
