Building newlib without -mhard-float

[Rick Mann]

Er, I meant

$ TARGET_CLFAGS="-march=armv5te -mcpu=xscale" make

Oh, okay. The reason I asked is that after I ran configure, I looked  
in the top-level makefile for TARGET_CFLAGS and couldn't find it.  
Should I just do it like this?

TARGET_CLFAGS="-march=armv5te -mcpu=xscale"

Which brings up another question I've had before: should I just use - 
mcpu=xscale, or just -march=armv5te, or both? At one point, I got  
errors in something when I used both, saying that they were in  
conflict (IIRC--strikes me as incorrect).

TIA,
