Upgrade for https://www.openssl.org/news/secadv_20140605.txt
Just in case - there is no vulnerability that affects ecdsa signing or
verification.
The MITM attack vulnerability (CVE-2014-0224) may have some effect on
our usage of SSL/TLS.
As long as payment requests are signed (which is the common case), usage
of the payment protocol should also not be affected.
The TLS usage in RPC may be at risk for MITM attacks. If you have
`-rpcssl` enabled, be sure to update OpenSSL as soon as possible.
- Add 'g++' package (virtualbox images don't have this by default)
- Workaround for determinism in Qt5 resources
- Pass --disable-maintainer-mode --disable-dependency-tracking to
configure for libqrencode to avoid random errors about missing m4
directory
- Fix typo -with-pic -> --with-pic
It is not necessary to rebuild dependencies after this commit.
Fixes#3610 and #3612.
