HOSTCFLAGS: Should not be set the same as CFLAGS since CFLAGS may be for a completely different platform.  Use sane defaults like other configs/*/*/Make.defs.

ARCHCPUFLAGS: Depending on how the GNU compiler was built we may need -fno-stack-protector.  Since we always want it we can just default to specifying it instead of depending on the compiler default.

LDFLAGS: If compiling for a 32 bit target from a 64 bit platform we need to tell the linker to generate a 32 bit elf file with -m elf_i386.

Kinetis Ethernet and Freedcom-K64F:  PHY address was wrong.  Modified driver to try all PHY addresses and then only fail if the driver cannot find a usable PHY address.  MDIO pin must have an internal pull-up on the Freedom-K64F.

fixes to n25qxxx mtd driver for smartfs support, etc...

update stm32l476 disco to include init code for smartfs and nxffs for cases where those fs are included in build.

alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well).
Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults.
Trivial spelling changes in comments, etc.

Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver.

BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.

I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!
