For x86 architectures, binutils objcopy and strip can be used as such. For armv7 and aarch64, binutils doesn't recognize the architectures and refuse to touch the files. For most/everything that objcopy/strip do, the actual architecture doesn't really matter though. Therefore, provide a wrapper script and a minimal tool for editing PE executables, that change the architecture from armv7 and aarch64 to i686 and x86_64 respectively before invoking binutils, and change it back afterwards. In case the binutils tools are missing, just return a successful result without doing anything for stripping operations (previously, we had the <triplet>-strip tool symlinked to /bin/true, so this isn't any worse than before) and fail for other objcopy operations.
