No and yes :-)

I will reject this part. USE_PRIVATE_LIBGCC should only be needed on broken tool chains (at least that's the theory), and the default case is always to assume we live in a perfect world where all tools are working as they are expected to do.
PLATFORM_RELFLAGS += -fno-common -ffixed-r8 -msoft-float
-PLATFORM_CPPFLAGS += -march=armv5te +PLATFORM_CPPFLAGS += -march=armv5te -mabi=apcs-gnu
I could live with this part, if it was thoroughly tested and does not cause problems with the most frequently used tool chains (which I'm afraid it would - I think I remember that I saw errors or unexpected behaviour when using multiple, different "-mabi" settings).
Best regards,
Wolfgang Denk
