installdocs/*: Updated.
In preparation for Slackware AArch64:
The 'boardsupport' directory has been renamed 'platform'.
The sub directory 'u-boot' has been renamed 'bootware'.
Updated asset URLs references accordingly.
You do not need to change anything - these changes affect the documented
installation process only.

Important note: glibc now requires a minimum of Linux 5.10.
Ordinarily the minimum Kernel requirement set to support earlier Linux
Kernels. However, as with the Slackware AArch64, this port of Slackware
(hardware floating point, 32-bit armv7) has never had a stable release, so
there's no requirement to support upgrades from any previous version of the
OS so it makes sense to set to the latest running Kernel.
If you are running a local build of the Kernel on Slackware ARM, you'll need
to ensure that you upgrade the Kernel if necessary before applying this glibc
update.

• a/aaa_glibc-solibs-2.33-arm-2.txz
• d/Cython-0.29.22-arm-2.txz
  Recompiled to fix building some programs that use Cython. It's possible
  that this was due to an ABI bug that shipped in Python-3.9.3, but we'll
  rebuild to be on the safe side.
  Thanks to PiterPunk who noticed this issue on 32-bit.
