I just compiled master-6e1207475b6942a3 natively on Arndale-Linaro
with the following settings. Note the change of CMAKE_ASM-ATT_FLAGS to
CMAKE_ASM_FLAGS to match the previously mentioned cmake commit.

cmake ../ -DCMAKE_C_FLAGS="-march=armv7-a -mthumb-interwork
-mfloat-abi=hard -mfpu=neon-vfpv4 -mtune=cortex-a15"
-DCMAKE_ASM_FLAGS="-march=armv7-a -mthumb-interwork -mfloat-abi=hard
-mfpu=neon-vfpv4 -mtune=cortex-a15"

In this case, the native gnuradio build in tmpfs took a very
reasonable, IMO, 42 min 31 sec.
