Hello Manuel,
life is strange ;-). I've tried a similar approach yesterday
evening, had the test build finished today and just wanted to
send off the bugreport when I have received your mail. A timeout
increase to 300 seconds looks good - in my test builds on an
otherwise idle system, the longest test took ~100 seconds, so 300
seconds should provide a reasonable security margin for a loaded
buildd.
Regarding stuff missing in unstable for properly debootstrapping
a system: there is at least one other package, and that is
libffi, which is used by apt. Unfortunately upstream support for
RISC-V is only available in libffi git head, but not yet in an
official release. Upstream had originally planned to release a
new libffi version (3.3) in May 2018, but that didn't work out
and AIUI there are a number of (not riscv64-related) regressions
compared to version 3.2.1 that need to be sorted out before a
release can happen.
Another package that is currently only in unreleased and which is
required at least for debootstrapping with --variant=buildd is
elfutils. Elfutils actually builds fine but fails a number of
tests. Andreas Schwab (from SUSE) has recently contributed some
RISC-V-related updates, but current elfutils git head still fails
some tests on riscv64. Unfortunately I know way too little about
ELF internals to debug those failures :-(.

Karsten
