This provides nano-second resolution times by reading the systick
value (which runs at 250ns ticks on stm).

Make sure AO_TICK_TYPE is used "everywhere", instead of uint16_t or other.

altos: Fix ISR declarations to make them non-weak2019-02-22T03:40:08+00:00Keith Packardkeithp@keithp.com2019-02-22T03:26:41+00:00urn:sha1:3310b22e28d953a6569cd50e83f91c25577424a5
In my zeal to eliminate warnings, I added declarations of all ISR
functions to a shared header file. However, I managed to include the
'weak' declaration, which meant that the intended ISR functions were
as weak as the 'default' ISR functions. This left all interrupts
non-functional, which doesn't make for a happy program.

This cleans up the build process for all architectures, providing a
common place to specify vpath, cflags and build rules for various
common files.

Support -Wcast-align and -Wpointer-arith while still allowing
architectures to pick whether they want an 8-bit or 32-bit stack.
