If I remove the line
#define INIT_SECTION_ASM_OP
in gcc/config/darwin.h, bootstrap fails at

INIT_SECTION_ASM_OP is meant to be a string constant, not empty. Try
defining it to "". I suppose the cases in libgcc that actually use the
string constant value inside asm, rather than just testing whether it's
defined, don't get used for Darwin?

That's about undefining it. I suggested keeping it defined, but changing
the definition from empty to "". You should, however, examine the code
paths used in libgcc to convince yourself that
__LIBGCC_INIT_SECTION_ASM_OP__ does not actually get used as an asm
argument on Darwin (either directly or via CRT_CALL_STATIC_FUNCTION) -
though if it did get used, I'd have expected you to have got syntax errors
from asm () before my patch. (As far as I know, asm () is not valid
syntax anywhere.)
