1. Use lib/libm for small (non-Express builds) to gain back a lot of flash space.
...
2. Add flag INTERNAL_LIBM to mpconfigboard.mk files to signal using lib/libm.
3. Fix floating-point warnings in lib/libm
4. Turn off -finline-limit, no longer needed due to 1.
5. Add explicit flags for SPI_FLASH_FILESYSTEM and INTERNAL_FLASH_FILESYSTEM
to mpconfigboard.mk files, so they don't need to know the name of the .c file
that implements those. Makefile takes care of checking the flags and including
the right files.

atmel-samd: Use link time optimization to reduce code size of builds which
...
share space with the file system.
"Express" builds with SPI flash crash the compiler for some reason so its
currently disabled for them.

atmel-samd: Rework mass storage interaction with underlying block
...
storage to use micropython's VFS interface.
This makes mass storage work with any VFS implementation rather
than a single one.

atmel-samd: Rename Feather M0 Bluefruit files to Feather M0 Basic because there isn't anything Bluefruit specific yet.
