--- Comment #25 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
you might consider adding something like that to your patch:
Index: elf.h
===================================================================
--- elf.h (revision 268337)
+++ elf.h (working copy)

+%{mfloat-abi=*} %{!mfpu=auto: %{!mfpu=none: %{mfpu=*}}} \

#endif
otherwise using -mfpu=none won't work on the command line.
becuse gas does not understand it.
