Make fiber_pool more conservative on platforms with limited address space.
...
We use COROUTINE_LIMITED_ADDRESS_SPACE to select platforms where address
space is 32-bits or less. Fiber pool implementation enables more book
keeping, and reduces upper limits, in order to minimise address space
utilisation.

518adcca0a: "Try using arm32 implementation for fibers."
dbe232e24e: "Order of arguments might be incorrect in arm32 coroutine implementation."
It seems to cause SEGV consistently on Ubuntu armv7l eabihf:

Change Makefile rule for assembly to use .S rather than .s
...
It is more conventional to use compiler to pre-process and
assemble the `.S` file rather than forcing Makefile to use `.s`.
