Patrick Georgi b3311c23b1 Use gcc's name for ARMv6-with-svc on cortex-m chips

There were various longer discussions[0] over in gcc land and the
consensus pretty much is that gcc's "armv6-m" shouldn't really exist,
or rather map to its armv6s-m.

Cortex-M0 is documented as having the svc instruction[1], and we make
use of it, so let's go for armv6s-m as the safe option.

We need that on some compilers (gcc 7, gcc 8.1.0) since they actually
make that distinction. Newer ones won't, older ones apparently didn't.
