Both architectures are variants of the ARM architecture and use the same
toolchain.
There is no reason to have such wildly different defaults.
This results in some tests passing that would crash before:
- [x] `tests/pkg_libcose`
- [x] `tests/pkg_qdsa`
- [x] `tests/pkg_relic`
- [x] `tests/pkg_tweetnacl`
- [x] `tests/pthread_tls`
`THREAD_EXTRA_STACKSIZE_PRINTF_FLOAT` is not used anywhere in RIOT
anymore, so just drop it.
puf_sram only relies on an uninitialized chunk of memory.
This means to enable it we just have to hook up puf_sram_init().
All memory after __bss_end should be uninitialized at startup, so
just use that.
At the time of configuration, the pthread-reaper uses '164' bytes of
stack when 'idle' stack is only '160'. By having double it gives some
margin.

- removed ISR_STACKSIZE define where unused (set to 0)
- removed thread_arch_isr_stack_usage(), thread_arch_isr_stack_start(),
and/or thread_arch_isr_stack_pointer() where not implemented
