Jeff Epler 4bae29b925 nrf: enable link-time optimization 
Testing performed: installed freshly built .uf2 on a Particle Xenon.
Checked that circuitpython still starts.
Checked that the size of all .uf2 files for nrf builds are plausible.

Aside from memory savings, the performance of Python code (pystone)
increased by about +14%.

However, this adds about 12-16 seconds to each nrf build.

Timings & Sizes (build system: i5-3320M, -j5 parallelism on 4 threads):
