armv7 binaries are compiled for armv6

[bnoordhuis]

$ strings node-v8.3.0-linux-armv7l/bin/node | grep arm_version
                 'arm_version': '6',

It's not new, see nodejs/node#4531 (comment).

Copying @rvagg 's comment from nodejs/node#4531 (comment)

Thanks for reporting this @igorklopov, I'm a little surprised this went unnoticed for so long. I can confirm your analysis and I've traced it to the fact that we're using Raspbian to get gcc 4.8 on the machine we're using to compile these binaries even though it's a vanilla Debian Wheezy armhf base, and of course Raspbian is armv6 so we get #define __ARM_ARCH 6 from the compiler...

Doh!

Which means we need to go back to finding a Wheezy armhf gcc 4.8(+) source or build one ourselves (which I think I did in the past but that's such a nightmare).

@XadillaX are you still working on this (see nodejs/node#4531 (comment))?

[rvagg]

🤦‍♂️ this is technically stalled and it's my fault. I have a server running on scaleway with custom compiled 4.9 gcc packages that I was going to install on those other boxes. I stalled on trying to figure out where to store these packages so they can be reused when reprovisioning the boxes, I don't really want to check them in to this repo.

Don't worry @rvagg, all we have our private lives and sometimes it gets busy :-)

[XadillaX]

@gibfahn Yes but slow progress due to my poor PI3.

@rvagg does it make sense to put those on the ci under the download user like we are for packages needed for other platforms ?

I think it would be a good idea. Would it be possible to also have downloads of binaries compiled with other standard C libraries beside glibc, like musl?

To be clear, @rvagg was talking about putting the gcc versions he compiled himself on https://ci.nodejs.org/downloads/. If you're talking about Node compiled with musl, then that'd be a different thing, and probably worth a separate issue.

Separate question, other than glibc and musl, are there any other C standard libraries in common use?
