Support and use SPE float instructions on Turris 1.x

HBL compatible version of !542 (merged)

Should enable Turris 1.x uboot build.

Older version of the branch tested with similar results as the merged HBD branch (except for more failing package builds; no problems with reForis, because it's not broken in HBL). Current version is just being built in burstlab. Needs proper testing, especially the update process reliability.

Useful to be included in TOS 6.0 because the target CPU architecture change will lead to all packages being reinstalled.

TODO:

• make important packages compile
  • liggpg-error and dependencies
• make less important but useful packages compile
  • gcc
  • freeradius3
• test medkit
• test update
• check nothing was broken for Omnia and Mox

changed milestone to %Turris OS 6.0

added Feature HW support Turris 1.x labels

requested review from @jschlehofer

Needs proper testing, especially the update process reliability.

If you'd be satisfied with the testing, which I am sure you will do, then feel free to merge this and then enable job for Turris 1.x in Jenkins.

There are some important packages (libgcrypt, vpnc, ntfs-3g) which cannot be built after the change. Builds of them crash because libgpg-error cannot be built. I'll try to fix that.

Last attempt at switch-branch from hbl to pre libgpg-error fix and rebase burstlab build lead to inaccessible reForis and luci. Certainly not ready for merge yet.

No widely used packages' builds fail after the fix. Seems good enough for HBL in this regard.
