FTBFS bug fix for llvm-gcc-4.2-2.5. While linking cc1-dummy:
libbackend.a(arm.o): In function `current_file_function_operand':
/home/martin/arm/llvm-gcc-4.2-2.5/build-gcc/gcc/../../llvm-gcc-4.2-2.5/gcc/config/arm/arm.c:3506: undefined reference to `ENCODED_SHORT_CALL_ATTR_P'
libbackend.a(arm.o): In function `arm_is_longcall_p':
/home/martin/arm/llvm-gcc-4.2-2.5/build-gcc/gcc/../../llvm-gcc-4.2-2.5/gcc/config/arm/arm.c:3581: undefined reference to `ENCODED_LONG_CALL_ATTR_P'
collect2: ld returned 1 exit status
Definitions fished out of the 2.2 release.
