--- Comment #5 from Maxim Kuvyrkov <mkuvyrkov at gcc dot gnu.org> ---
No need to rebuild the whole GCC with -save-temps.  Just go to directory where
compilation of extenddftf2_s.o takes place and copy-paste the compilation
command for that one file with addition of -save-temps.

I'm not familiar with "Apple Inc version cctools-862, GNU assembler version
1.38", so it may be that assembler is broken or too old; you may have to build
recent binutils for your GCC to use.
