[AVR] Missing avr51-flash1.x in avr target specific tests?

[Senthil Kumar Selvaraj]

Some tests in gcc/testsuite/gcc.target/avr/torture (builtins-2.c, for
e.g.) have -Tavr51-flash1.x specified in dg-options. The tests currently
fail with an unable to open linker script error for that file.

Is that linker script supposed to be checked into source control? Or am
I missing some configure/build option?
