--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I was able to compile and test GCC myself with the following options:

apinski@Andrews-Mac-mini ~ % ~/upstream-gcc/bin/gcc -v
Using built-in specs.
COLLECT_GCC=/Users/apinski/upstream-gcc/bin/gcc
COLLECT_LTO_WRAPPER=/Users/apinski/upstream-gcc/libexec/gcc/aarch64-apple-darwin20.4.0/11.0.1/lto-wrapper
Target: aarch64-apple-darwin20.4.0
Configured with: /Users/apinski/src/upstream-gcc-macosx/gcc/configure
--prefix=/Users/apinski/upstream-gcc
--with-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/
Thread model: posix
Supported LTO compression algorithms: zlib
gcc version 11.0.1 20210417 (experimental) (GCC)
apinski@Andrews-Mac-mini ~ % ~/upstream-gcc/bin/g++ t.c
apinski@Andrews-Mac-mini ~ % ./a.out
Hello World.
apinski@Andrews-Mac-mini ~ % cat t.c
#include <iostream>

int main(void)
{
  std::cout << "Hello World.\n";
}
