OBJCXX's std flags don't get defined by our cxx macro. Rather than hard-coding
to c++11, just force OBJCXX to be the same as CXX unless the user specified
otherwise.
We don't use any elliptic curves from OpenSSL anymore, nor include this
header anywhere but optionally in the tests of secp256k1 (which has
its own autoconf setup).

- guard PKG_PROG_PKG_CONFIG with an m4_ifdef. If not building for windows,
require it
- add nops as necessary in case the ifdef reduces the if/then to nothing
- AC_SUBST some missing _LIBS. These were split out over time, but not all were
properly substituted. They continued to work if pkg-config is installed
because it does the AC_SUBST itself
This was caused by an pyc files hanging around from previous
python2 invocations, when the matching .py missing from that path.
This should not be a problem with python3's tagged caches.
- clear the __pycache__ during 'make clean'
- Copy the qrc locale file to a temp location and remove it when finished
(rcc expects everything to be in the same path)
Disabling warnings can be tricky, because doing so can cause a different
compiler to create new warnings about unsupported disable flags. Also, some
warnings don't surface until they're paired with another warning (gcc). For
example, adding "-Wno-foo" won't cause any trouble, but if there's a legitimate
warning emitted, the "unknown option -Wno-foo" will show up as well.
Work around this in 2 ways:
1. When checking to see if -Wno-foo is supported, check for "-Wfoo" instead.
2. Enable -Werror while checking 1.
If "-Werror -Wfoo" compiles, "-Wno-foo" is almost guaranteed to be supported.
-Werror itself is also checked. If that fails to compile by itself, it likely
means that the user added a flag that adds a warning. In that case, -Werror
won't be used while checking, and the build may be extra noisy. The user would
need to fix the bad input flag.
Also, silence 2 more additional warnings that can show up post-c++11.
The NSIS script tried to delete wxwidgets-based executables/locales. These files are ancient, and presumably no users have them anymore, so we can simplify the NSIS script by removing those lines.
Replaces the hardcoded string "bitcoin" with the autoconf variable PACKAGE_TARNAME; fixes#7265.
Places where I chose not to replace:
1. bitcoin.ico wasn't replaced because it doesn't seem to be relevant to the build system and its filename never affects the end user.
2. InstallDir wasn't replaced because the current text has an uppercase B, and I'm not sure of a good way to capitalize the result of PACKAGE_TARNAME.
3. A comment in the Main Installer section wasn't replaced because comments don't ever face the end user.
4. The registry value "URL:Bitcoin" wasn't replaced for the same reason as InstallDir.
5. Startup shortcut wasn't replaced for the same reason as InstallDir.
All other appearances of "bitcoin" were replaced with PACKAGE_TARNAME, except for the bin names, which were instead replaced with the new bin name autoconf variables.
