Fixes default hidden symbol visibility for our linux->osx cross build. Without
this change, the check for working -fvisibility=hidden fails, and all symbols
are visible by default.
Ugly as this is, it's just a simple find/replace to fix a bug in Qt's configure.
They assume in an "XPLATFORM_MAC" block that the builder is capable of running
osx programs. This should be "BUILD_ON_MAC" instead.

Descriptors now make use of the dependencies builder, so results are cached.
A very new version (>= e9741525c) of Gitian should be used in order to take
advantage of caching.

We're not ready to switch to a static qt5 for Linux yet due to missing plugin
support. This adds a recipe for building a shared qt4 that we build and link
against, but don't distribute.
make USE_LINUX_STATIC_QT5=1 can be used to build static qt5 as before.
|
|
This avoids textrels, and matches previous gitian behavior.

qt needs to be rebuilt for travis. The previous commit should help ensure that
this won't need to be done again.

tl;dr: This solves boost visibility problems for default/release build configs
on non-Linux platforms.
When Bitcoin builds against boost's header-only classes, it ends up with
objects containing symbols that the upstream boost libs also have. Since
Bitcoin builds by default with hidden symbol visibility, it can end up trying
to link against a copy of the same symbols with default visibility.
This is not a problem on Linux because 3rd party static libs are un-exported
by default (--exclude-libs,ALL), but that is not available for MinGW and OSX.
Those platforms (and maybe others?) end up confused about which version to use.
The OSX linker spews hundreds of: "ld: warning: direct access in <foo> to
global weak symbol guard variable for <bar> means the weak symbol cannot be
overridden at runtime. This was likely caused by different translation units
being compiled with different visibility settings."
MinGW's linker complains similarly.
Since the default symbol visibility for Bitcoin is hidden and releases are
built that way as well, build Boost with hidden visibility. Linux builds Boost
this way also, but only for the sake of continuity.
This means that the linker confusion logic is reversed, so the problem will
will now be encountered if Bitcoin is built with --disable-reduce-exports, but
that's better than the current situation.

Bumps the OpenSSL version to the latest release, and kills SSL2. (SSL3 was already killed here, so I'm not sure why SSL2 was left around?)
No other changes.

Newer mingw supports the features necessary to enable this api, whereas older
versions didn't. However once enabled (automatically by configure), it triggers
an unrelated build bug.
Since it was not enabled previously anyway, and we don't depend on the
functionality, just disable it across the board.

This means it also needs to honor our flags, so patch them in as necessary.
|
|
Also hook up cppflags there, which was missing before.
