Fixes running x64 binaries on arm64 hosts, this fixes systems like Raspberry Pi's, Apple Silicon, and Ampere. Before, I would get something like: ``` Checking GN formatting... Completed checking 0 GN files with no formatting problems. Checking Java formatting... No Java files with changes, skipping Java format check. Checking Python formatting... All python files formatted correctly. Checking for trailing whitespace on 1 source file... No trailing whitespace found. No header files with changes, skipping header guard check. Checking C++/ObjC/Shader formatting... ERROR: Formatter command '/home/ross/flutter-engine/src/flutter/buildtools/linux-x64/clang/bin/clang-format --style=file shell/platform/linux/fl_application_test.cc' failed with exit code 255. Command output follows: qemu-x86_64: Could not open '/lib64/ld-linux-x86-64.so.2': No such file or directory Completed checking 0 C++/ObjC/Shader files with no formatting problems ``` Now it just works, I also changed the shell script to use env since `/bin/bash` doesn't exist on NixOS so using env is a more portable solution. *List which issues are fixed by this PR.
