For MacOS and Windows I think that it defines -DBIT_IDENTICAL_FLOATING_POINT=1:

CFLAGS:=$(CFLAGS) -DBIT_IDENTICAL_FLOATING_POINT=1

That can be seen in 

./build.macos64x64/common/Makefile.flags
./build.win64x64/common/Makefile.tools

and then it adds fdlibm/libm.a:

ifdef BIT_IDENTICAL_FLOATING_POINT
LIBS:=$(LIBS) $(BLDDIR)/fdlibm/libm.a
endif

So I think that if you set -DBIT_IDENTICAL_FLOATING_POINT=0 on MacOS,
then it stills adds fdlibm/libm.a (because it is defined as '0')

So regardless of whether you set it '0' or '1', it adds fdlibm/libm.a right ?
