 hoichess fails to cross build from source for some combinations of 
 architectures, because it passes host compiler flags to the build 
 compiler. This is a bit non-obvious. hoichess is generally well-equipped 
 for cross building and has special provisions in book/Makefile to 
 support it. Specifically, it recursively calls itself with a replaced 
 compiler to build tools to be run during buil. It terms these 
 "build/host/", which may cause confusion with the GNU terminology used 
 by Debian. In doing so, it appens the flags for the native compiler 
 rather than replacing them. When cross building for e.g. arm64, flags 
 such as -mbranch-protection=standard are thus kept and the native 
 compiler fails to understand them. I'm attaching a patch to turn the 
 appending into replacement and that fixes the cross build.
