thanks Zoltan, the changed FPU setting made that early abort vanish when that
commandline switch is enabled. at least now i am getting bombarded with an
insane amount of prints per second at that layer. ;-)
i am still wondering why no-FPU is a no-go for that ARM platform as i expected
the mono runtime to be a bit smarter or more clear in that respect. maybe thats
something that can be improved e.g. an explicit check on compatibility of the
runtime that fails with a clear message.
maybe the last build tricked me in believing its the very same problem as
initially described, thus stroke --trace=all and the FPU setting.
the bad side after re-testing - the glibc list corruption persisted.
it still looks like that any now and then:

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
