DSP: Fix bug in scaled non-power-of-2 fixed-point FFT
Without this patch, the non-power-of-2 fixed-point FFT does scale
the output even when the scaled_flag is set to 1.

aarch64: Enable build for aarch64 GNU Linux
Enables build configuration to be able to build Ne10
for aarch64 GNU Linux.
Eg: build instructions:
mkdir build && cd build
export NE10_LINUX_TARGET_ARCH=aarch64
cmake -DCMAKE_TOOLCHAIN_FILE=../GNUlinux_config.cmake ..
make -j6
Note: By default, NE10_LINUX_TARGET_ARCH will be set to
"armv7"
Also adds -funsafe-math-optimizations for ARMv7 GNU targets

* Ne10 supports scale of output for backward RFFT,
while pffft doesn't. To normalize the benchmark,
a scale operation was added to the end of each
call to pffft.
* pffft C2R FFT costs 410ms when size==32, 338ms when
size==64, this is because the former loops more times
than the latter does, so it does not mean pffft cost
more time for short input.
