How can I tell if a certain c++ library was linked using c++11 standard?

To see if your compiler has C++11 support, run it with just the --version option to get a print out of the version number. Do this for whichever compiler(s) you wish to use with Rosetta. Acceptable versions: GCC/g++: Version 4.8 or later.
C++17 Support in GCC C++17 features are available since GCC 5. This mode is the default in GCC 11; it can be explicitly selected with the -std=c++17 command-line flag, or -std=gnu++17 to enable GNU extensions as well.
An elf binary would by default contain the signature of compiler version used.
Now, with regards to compiler flags used, If -frecord-gcc-switches is used at compile time, then, you can find the signature in ELF executable.
g++ -frecord-gcc-switches -std=c++0x trial.cpp
readelf -p .GCC.command.line a.out
