arm: Make sel build with clang's built-in assembler.

clang's integrated assembler only supports UAL, where sp is spelled
sp and not %sp. Fixes the following error when building with clang's
integrated assembler enabled:

../../native_client/src/trusted/service_runtime/linux/arm/sel_segments.c:13:7: error: unexpected token in operand
  asm("mov %0, %%sp" : "=r" (sp));
      ^
<inline asm>:1:10: note: instantiated into assembly here
        mov r0, %sp
                ^
1 error generated.

arm: Make sel build with clang's built-in assembler.

clang's integrated assembler only supports UAL, where sp is spelled

integrated assembler enabled:

error: unexpected token in operand
  asm("mov %0, %%sp" : "=r" (sp));
