gcc-8.2 -O3 optimization enables -finline-functions.
For reasons yet unknown this causes issues with Glib::Threads::Private
when loading sessions (creating new ones is fine) and likely some
other operations.
Without this change the following happens (5.12 as well as current git)
when loading an existing session:

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
---
Note that in the trace starting at #19 the source-file references
are offset :post_engine_init() isn't in xml++.h
(likely debug symbols are incorrect due to inline functions)
The application crashes due to #2 ::flush_pending_with_ev (this=0x0 ..)
But the earlier breakpoint above shows that the ThreadPool was
created, and this #11 ::clear_events() should not assign NULL.
(This happens on a single-core CPU, too)

Otherwise this causes PBD::FPU to fail with
error: inlining failed in call to always_inline ‘long long int _xgetbv(unsigned int)’

Ardour's boost is not compiled --with-system, this causes issues
with modern compilers (gcc 8.2) when linking.

Collect architecture independent data in 'share' subfolder.
This also matches the install path

Libraries need to be specified in order as last argument,
not as linkflag.

* Windows: delete waf installed .dll.a files
* Windows: override waf's conf.env.LIBDIR = conf.env.BINDIR
with explicit --libdir
* Windows: fix asm (`x86_64-w64-mingw32-as` -D flag is for
debug messages, -D defines are not available)
* Mac: override waf adding -install_name (and
-Wl,-compatibility_version -Wl,-current_version)
by moving -dynamiclib from linkflags to ldflags
* Mac: Allow libs with compat version number suffix
(not needed anymore, but may help in the future)

Or a timestamp, but that's deprecated. Create it from the last commit,
store it in/retrieve it from revision.cc and substitute it in the
template.

While the pads work, overall integration is still not present, mainly
because the device does not lend itself for editing & mixing in a
DAW environment.

This simplifies x-compiling and x-platform builds as well
allows to statically link, if needed.

The previous code was supposed to ensure VERSION and PROGRAM_VERSION
were *not* Unicode objects since though they are the correct type to
represent strings in Python 2, too many libraries have strange issues
dealing with them, and UnicodeErrors can creep in with implicit
conversions from/to Unicode objects.
But in fact it did exactly the contrary since str.decode() always
returns Unicode objects, whose type corresponds to the str class in
Python 3. Fix it so that in both Python 2 and 3 the constants are
eventually instances of str.
