Max Filippov 2a26adf1d8 xtensa: don't use unwind-dw2-fde-dip with elf targets
Define LIB2ADDEH_XTENSA_UNWIND_DW2_FDE to unwind-dw2-fde.c in
xtensa/t-elf and to unwind-dw2-fde-dip.c in xtensa/t-linux and use
LIB2ADDEH_XTENSA_UNWIND_DW2_FDE in LIB2ADDEH definition.

This fixes build for elf target with windowed xtensa core that currently
breaks with the following error message:
    
  unwind-dw2-fde-dip.c:36:40: fatal error: elf.h: No such file or directory
