Attaching relevant part of gmake log:
[+] llvm_mode detected llvm 10+, enabling neverZero implementation and c++14
[+] llvm_mode detected llvm 11+, enabling afl-lto LTO implementation
[+] shmat seems to be working.
[*] Checking for working 'llvm-config'...
[*] Checking for working '/usr/local/llvm11/bin/clang'...
[*] Checking for matching versions of '/usr/local/llvm11/bin/clang' and 'llvm-config'
[*] We have llvm-config version 11.0.1 with a clang version 11.0.1, good.
[*] Checking for './afl-showmap'...
[+] All set and ready to build.
