- remove unused alex
- streamline Link's config
- remove misleading Daisy config:
1) armv7=1 does nothing. We meant to type arm_version=7 here.
2) arm_neon=1 does nothing unless arm_version == 7.
3) arm_thumb=0 is the default when arm_version <= 7.
4) skia_arch_width=32 is the default when skia_arch_type=arm.
I'd just fix this to make Daisy arm_version=7 and arm_neon=1 (and
arm_thumb=1, which I'm going to separately make the default for
arm_version=7), but there are known color-order bugs with our
NEON procs that would make Daisy start pushing bad images to
Gold. Going to take baby steps here...
