This is an excerpt of the gcc commandline from pixman:

arm-angstrom-linux-gnueabi-gcc \
-march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp \

I split it between what I'm using when building for armv7a and what 
pixman adds. So pixman adds too little to be usefull and what it adds is 
not right for the target I'm targetting. Can we please add a 
--I'm-using-ARM-but-actually-know-what-I'm-doing configure switch to 
disable this behaviour?
