comment How to use my cross-compiler to compile something?
"File in wrong format" sounds like either (1) you previously built for the native platform and now that file is interfering with the cross build for the other platform. Best to "make clean" after changing platforms. Or (2) the Makefile is incorrectly building some targets for the native platform and others for the cross platform. Even though you specified an alternate compiler maybe a native platform compiler is hardcoded somewhere in the Makefile. For that, you're have to find what needs updating in the Makefile and improve it.

comment How to use my cross-compiler to compile something?
"even though you don't answer to my comments" — I'm sorry. Your first comment was related to not having installed the toolchain. Your second comment fixes that. Your third comment seems like it's a different problem, maybe specific to whatever software you're trying to build, but cannot be answered without more details about what "not creating the necessary files anymore" means. Your other comments I didn't see until just now, owing to having been busy travelling.

comment It is possible to run these in GNU parallel
Please explain a little better what you are trying to do. You have listed 4 times the same command! Do you want to run this on 4 different hosts? Do you really want to start 4 screen sessions (not just 1)? These are interactive commands (hence the watch), it does not seem to make sense to run them in the background.

comment Cron only occasionally sends e-mail on output and errors
I think the answer is close to what you said, but actually a race between the subshell and cron. Since the subshell is backgrounded, cron stops listening to it promptly. But occasionally it manages to squeeze out its error message very quickly while cron is still listening.

comment setting up subdomain at centmin mod
Don't forget to add a AAAA record also when you add an A record. It's 2015, IPv6 is decades old and it's about time it received as much attention as its address-exhausted older sibling! :-)

comment Can one ping a NIC by MAC
+1 — this is the only answer that truly addresses the OP's question. "Wake-on-LAN is unidirectional".

comment why do queries with status “refused” get answers?
I believe that's definately odd. It could be a broken DNS server or a DNS firewall rewriting status codes? Please provide more information about DNS server software and the network path between the DNS client and DNS server. If possible, perform this query directly on the DNS server itself with dig @127.0.0.1 (or whatever IP address it is listening on).

comment Why are my OpenSSH keys stored in OpenLDAP returned base64 encoded
No, you're not doing anything wrong. Using sed to parse LDIF is the wrong tool for the job. It may work 95% of the time but that's not enough. I can see that the sed command in the page you linked assumes no double colon and no base64, but it is not allowed to assume that.

comment Can bash shells automatically recognize Gnome terminal window's width?
bash has nothing to do with it. It's the actual terminal that's doing that.

comment sftp (ssh_exchange_identification: read: Connection reset by peer)
The server is accepting the TCP connection but closing it again before any SSH protocol interaction has a chance to occur. This commonly happens if the SSH server is crashing right after accepting the connection, for example.

comment Insert both characters if a dead key combination is not recognized (e.g. 'a → á, 'b → 'b)
Note that <Compose>'b is a poor example, because there are actually valid compose sequences that begin with those characters, for example <Compose>'ba leads to .
