distro: trixie: Add riscv64 to supported architectures

[ColorfulRhino]

Add riscv64 to supported architectures for Debian Trixie.

How Has This Been Tested?

• Try compiling minimal Trixie image: Add board BananaPi F3 #6771 (comment)
• There is currently another issue with the base-files: Could not find package filename for 'base-files'  #6790

Checklist:

• My code follows the style guidelines of this project
• I have performed a self-review of my own code
• My changes generate no new warnings

if it can be assembled, lets bring it in

There are some dependency warnings like

dpkg: libpam-modules-bin: dependency problems, but configuring anyway as you requested:
 libpam-modules-bin depends on libaudit1 (>= 1:2.2.1).
 libpam-modules-bin depends on libcrypt1 (>= 1:4.3.0).
 libpam-modules-bin depends on libpam0g (>= 0.99.7.1).
 libpam-modules-bin depends on libselinux1 (>= 3.1~).
 libpam-modules-bin depends on libsystemd0 (>= 254).

Setting up libpam-modules-bin (1.5.3-7) ...

But it seems to assemble it anyway, apart from the base-files problem. I just assume this is normal behaviour normal for RISCV64.

I think those warnings are safe to ignore. Base files problem is really annoying ... damn. What about making a mirror of whole ubuntu packages ? How much we need?

[ColorfulRhino]

Actually no, I may have confused the failure for being base-files related, but this is the actual cause I believe:

   dpkg: error processing package apt-utils (--configure):
    dependency problems - leaving unconfigured
   Errors were encountered while processing:
    apt-utils
   dpkg: dependency problems prevent configuration of apt-utils:
    apt-utils depends on libgcc-s1 (>= 4.3); however:
     Package libgcc-s1 is not installed.
    apt-utils depends on libstdc++6 (>= 13.1); however:
     Package libstdc++6 is not installed.

After inspection, those needed packages e.g. libgcc-s1 is missing an riscv64 package for Trixie: https://packages.debian.org/trixie/libgcc-s1
But it's avaibale in Sid.

revert?

[ColorfulRhino]

revert?

Yeah probably better than trying to pick some specific packages from Sid.
Let's wait if they will add riscv64 versions for those packages in Trixie or if RISC has to wait a while to get Debian.

I'll send a quick revert.

[ColorfulRhino]

Sid builds just fine without these warnings, so yeah Trixie is not yet ready for RISV64 :)
Sorry for the hassles! I'm just trying to help with #6771 (I do not own the board) to keep the PR and the commits sane/raise the bar for quality a bit :)
