GCC 8.x is required to avoid the following error:
cc1plus: error: -Werror=class-memaccess: no option -Wclass-memaccess
If we build without "-Wno-error=class-memaccess" the build should fail
and the upstream requirements were raised from GCC 7 to GCC 8 anyway:
b2f821d3de
The two additional patches are required to avoid build errors like this:

Whenever we create scripts that are installed to $out, we must use runtimeShell
in order to get the shell that can be executed on the machine we create the
package for. This is relevant for cross-compiling. The only use case for
stdenv.shell are scripts that are executed as part of the build system.
Usages in checkPhase are borderline however to decrease the likelyhood
of people copying the wrong examples, I decided to use runtimeShell as well.
TODO: We're still using the old API ID (like the Arch package) which
should be used for testing only.
I've tried to contact the Telegram team multiple times via different
channels but didn't get a response so far. See [0],[1] for more details.
