What you want to do isn't currently supported in a single configure/build.  If you can't
override flags for the gcc build, you will have to do more than one build.  Otherwise,
if you can override flags, you could try a configure-target-newlib, change into newlib
directory and do a make stmp-targ-include, then add the flags
to the all-gcc make call to point to the newlib target includes.
