On some systems, such as the Apple M1 (ARM-based Macs),
dylibbundler is in $PATH, but not in a directory found by the limited
path that SCons uses for Command() invocations. This causes the SConf
test to succeed (because it uses the full $PATH), but the Command() to
fail (because it uses a reduced path). Fix this by using the user's
$PATH, if defined, for this Command() invocation.
Along the way, rework tool_bundle.py to use SCons' Node() objects in
place of direct path manipulation. This lets SCons produce better error
messages in some cases.

When joystick support is not present, `event_joystick_get_button` is not
declared in joy.h.
Fixes: c24864b180 ("make menus controllable with joystick")
Testing for buttons||hats||axes is equivalent to testing for
joysticks!=0, since SConstruct forces joysticks=0 when
buttons == 0 && hats == 0 && axes == 0. Remove tests of
buttons||hats||axes when those occur inside a test for joysticks!=0.
If axes!=0 and buttons==0 and hats==0, then the build fails because some
button-related functionality is missing. Move the joystick axis->button
bridge into a conditional to exclude it in this case.
Fixes: 74ef8b02e6 ("Added axis buttons")
Instead of parsing the button name string,
an explicit button-to-key mapping table
is now built and used.
Also fixes a few minor inconsistencies
that were introduced in c24864b1.
In most menus, keyboard commands are synthesized
from controller buttons, leveraging the existing
axis-to-button translation.
Menu controls are currently fixed:
- button 0 (A) is confirm (Enter)
- button 1 (B) is cancel (Esc)
- button 2 (X) is switch (Space)
- button 3 (Y) is delete (Delete)
- axes 0 and 1 (main analog pad) maps to cursor keys
- all hats (D-pads) map to cursor keys
Title screens and credits can be confirmed
with any joystick button or axis motion too.
mmontag reports that tool_bundle.py cannot be parsed under Python 3.
Fortunately, the errors are all straightforward, so non-OS X systems can
see the errors when the file is imported. Normally, the file is only
imported when building for darwin, so non-OS X systems do not see the
problem.
- Add parentheses to print() calls. This is not consistent with the
rest of the Rebirth output scheme, but is simple to do.
- Adjust the syntax for raising exceptions.

The minimum supported compiler versions now provide a depth-efficient
implementation of std::make_index_sequence, which removes the last
reason to carry a private implementation. In the case of clang, it
appears to have a special compiler intrinsic used to implement its
std::make_index_sequence.
Switch to the compiler-provided version for both gcc and clang.
