commit acafc78e88380a3f98c307626ba1b67a9f4a122f
Author: Stefan Reinauer 
Date:   Fri Jul 31 13:50:03 2015 -0700

Move function/data sections to common CFLAGS

Instead of adding -ffunction-sections and -fdata-sections to
    every architecture, just add it to CFLAGS_common, thus making
    sure that new architectures will pick it up automatically.
