Commit: Fix building ld/emultempl/avrelf.em with clang

[Nick Clifton]

Hi Guys,

  I recently came across this build error when using clang instead of
  gcc on a toolchain configure with --enable-targets=all:

    eavr1.c:104:7: error: use of logical '&&' with constant operand [-Werror,-Wconstant-logical-operand]
        && strcmp ("avr1","avrxmega6")
        ^  ~~~~~~~~~~~~~~~~~~~~~~~~~~~

  So I am checking in the patch below to fix the problem.

Cheers
  Nick
