Configure for armv6 doesn't disable neon and armv6t2.

[danergo]

I'm trying to configure ffmpeg for rpi1 (armv6).

First, I have modified this line: ​https://github.com/FFmpeg/FFmpeg/blob/master/configure#L8021

From echo "ARCH $arch ($cpu)"
To echo "ARCH $arch ($cpu) $subarch"

In case I'm doing a configure with these parameters:
./configure --enable-cross-compile --cross-prefix=arm-linux-gnueabihf- --arch=armv6z --cpu=arm1176jzf-s --target-os=linux:

source path               src
C compiler                arm-linux-gnueabihf-gcc
C library                 glibc
host C compiler           gcc
host C library            glibc
ARCH                      arm (arm1176jzf-s) armv6
big-endian                no
runtime cpu detection     yes
ARMv5TE enabled           yes
ARMv6 enabled             yes
ARMv6T2 enabled           yes
VFP enabled               yes
NEON enabled              yes

As you can see: $subarch is printed and it's correctly set to armv6.

However, neither "ARMv6T2" nor NEON are disabled.

NEON instructions are guarded by runtime cpu detection, it works by design. If you find anything doesn't work as expected, please provide the compiler information and config.log.
