Add UFS2 support, with libsa for boot and with a specific ufs-and-ufs2-in-one
flavour for xxboot, due to its size constraints.

Build libsa with NO_NET as we don't need any of the network-related code in it.

Force compilation to fail in case of implicit function declaration.

need ashrdi3

Prep for relro: make sure it's off for any non-PIE stand/ program

ok millert@ kettenis@

No need to create {sd,wd}boot links to xxboot anymore.

Build required bits from libkern rather than importing them from libgcc.

fix even more trailing tabs

Cope with pie-by-default, if it ever happens; ok pascal

Add NOPIE= bits for sys/arch/*/stand to ensure that bootblocks will always be
built with -fno-pie. This gets the hairiest part of PIE out of the way ...

libkern, begone. Move to a new mechanism where config(8)'s "file"
directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.

There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.

Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

OBJCOPY should default to objcopy.

this is actually a primary bootblock (xxboot) not a secondary bootblock
(bootxx) thus disklabel -B will automatically pick it up now; ok drahn
