Don't define CTORS_SECTION_ASM_OP and DTORS_SECTION_ASM_OP on arm when
built with clang. When these are defined the lists are defined similar to:
asm(".section .ctors");
STATIC func_ptr __CTOR_LIST__[1] = { (func_ptr) (-1) };
asm(".section .dtors");
STATIC func_ptr __DTOR_LIST__[1] = { (func_ptr) (-1) };
The problem is clang will move the two arrays out of the .ctors and .dtors
sections causing these sections to contain a single null address. By not
defining these macros we use the version of the code that places the arrays
is their sections by using __attribute__((section(".ctors"))) and similar
for .dtors.
