Support building internal libraries as shared. This reduces
development time by eliminating the need to re-link all
binaries every time non-interface code in the library changes.
Instead, can hack on libxyz, then `make libxyz`, and re-run
monerod.
By default BUILD_SHARED_LIBS is OFF in release build type,
and ON in debug build type, but can be overriden with -D.
It's only blank only if somebody running cmake in MSYS/MinGW (Windows)
manually forgets to add -D ARCH, but when it is blank, without quotes
those lines are invalid cmake syntax.
The split is to make this software more packageable. 'make install'
is used by the package building scripts, and should not be installing
vendored dependencies onto the system.

This reverts commit 8623492150.
Let's restrict ARCH to values accepted by -march to keep things clear
and consistent. ARCH is -march, with only one exception: a value of
"default" indicates to not pass -march at all.
It is not correct to do so, because ARCH should only take values
supported by the -march argument, with the exception of 'default'
which denotes not passing -march at all.
ARCH defines the target architecture for builds that are intended to be
portable to other machines.
This gets rid of bitmonerod.exe's dependecy on libwindpthreads-1.dll in build
on Windows on x86_64 (via MSYS2 default toolchain). With this patch all DLL
dependencies are on DLLs in c:\windows\system32.
The previous logic that used a COMMON_*_FLAGS intermediate variable
and then re-assigned CMAKE_*_FLAGS before including each subdirectory
was confusing and ugly. This PR is the right way to do it.
This commit is purely refactoring: built binaries unchanged.
By default the flag is enabled whenever libunwind is found on the
system, with the exception of static build on OSX (for which we can't
install the throw hook #932 due to lack of support for --wrap in OSX
ld64 linker).
This is an attempt to fix build with STATIC=ON on OSX (#932):
[ 95%] Linking CXX executable ../../bin/bitmonerod Undefined symbols for
architecture x86_64: "___real___cxa_throw", referenced from:
___wrap___cxa_throw in libcommon.a(stack_trace.cpp.o) ld: symbol(s) not found
for architecture x86_64
This fixes build of tests with STATIC=ON, which failed with:
/tmp/cc8lNtqY.ltrans12.ltrans.o: In function
`boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::thread_resource_error>
>::rethrow() const [clone .lto_priv.41]':
cc8lNtqY.ltrans12.o:(.text+0x4e): undefined reference to `__wrap___cxa_throw'
The hook is implemented in libcommon, which is not linked into some of the test
binaries. An alternative solution is to link all tests against libcommon,
but that seems worse because it introduces a false dependency (also,
I tried that and for some of the test binaries the linker still failed to
pick up the symol from libcommon, strangely.)
