When I tried the same (without that weird multi-stage build), I got 
probably in the same phase :

Ie the "-DFUNC=__addsf3 -DOP_add3 -DTYPE=sf" instead of your bare 
"addsf3" in the compile row...
The extra:

"-B/home/src/gcc-4.9.0/build/mips-sde-elf/newlib/ -isystem 
/home/src/gcc-4.9.0/build/mips-sde-elf/newlib/targ-include -isystem 
/home/src/gcc-4.9.0/newlib/libc/include 
-B/home/src/gcc-4.9.0/build/mips-sde-elf/libgloss/mips 
-L/home/src/gcc-4.9.0/build/mips-sde-elf/libgloss/libnosys 
-L/home/src/gcc-4.9.0/libgloss/mips"

came from having 'newlib' and 'libgloss' from the newlib-2.1.0 sources 
symlinked into the gcc-4.9.0 sources. Just
like the gmp, mpc and mpfr sources - building these for the target or 
the host during the GCC build. This is what
I meaned with the "single stage" build...

Still I cannot say what causes your problem on a OS X 10.7 host....
