Daily testsuite results are available for both armel (2.6.0/fixes and
2.7.0/trunk, for a long time now) and armhf (only 2.7.0, for a few weeks
for comparison, and
for specific results.
Basically the difference between armel and armhf are
- fpc cannot create valid armhf shared libraries
Other problems common to both (just from interpreting the testsuite
results, filtering known failing tests):
- there are issues with threading/synchronization (test machine is a
quad-core box, previous test machine was single core where as usual such
problems don't show up)
- fpu exceptions/setting fpu exception mask seem to not work
- some problems with fpc resources

The old build machine has only 64MB RAM (600 Mhz ARM11), so yes, it is
possible, although somewhat slowly.

Yes. Probably one of the first milestones for a new arch is self-hosting
(if possible at all).
