Add suport for deterministic armhf builds

Many people use development boards (Raspberry Pi 2, Banana Pi,
Odroid boards, etc) to run full nodes in CLI mode.

The only option they had until now is to compile their own from source.
Even though many tutorials are available, it is still not trivial for
non tech-savvy users.

Providing an officially built armhf binary would provide non tech-savvy
users an easy ramp-on to Bitcoin Classic.

*** GUI has been disabled for this build — according to Qt docs it
needs to be compiled on with device-specific headers. Most armhf users
use it in CLI mode only anyway.

Tested binaries on Raspberry Pi2, Odroid C1 and Odroid XU4.

Did you try this? I don't think this will work. (c.f. #7465)

So curl is not needed here?

It build just fine without it, but I'll add it for consistency.

If it is not needed, but needed in #7658, it should be removed for consistency?

Maybe, but not as part of this PR.

Gitian: fix check-symbols for armhf builds

amrhf builds leak Boost symbols, so @laanwj’s linker script hack was
added back to armhf builds.

Also added ld-linux-armhf.so.3 to the list of allowed libraries in
symbol-check.py.

Shouldn't this just be thrown into the linux descriptor?
jonasschnelli commented at 3:59 PM on March 9, 2016: contributor

I think @luke-jr point make sense (if its technically possible), because it will still be a "armhf" linux build I guess? But no strong opinion.

Agreed with @luke-jr. That descriptor was created to work with multiple archs. Either use a single descriptor for all, or break them all out.
theuni commented at 7:16 PM on March 9, 2016: member

Also, there should be no need for that linker script. Boost shouldn't be able to leak symbols because we use -Wl,--exclude-libs,ALL. Details on leaked symbols would be useful.
btcdrak commented at 8:12 PM on March 9, 2016: contributor

@theuni I agree, this should be rolled into -linux.yml
