The current build of the firmware relies on having 32bit compatible headers installed in order to build some of the 32bit firmware. Usually this can be solved by using the -ffreestanding compiler option which drops the usage of the system headers in favor of a private set of freestanding headers provided by the compiler itself that are not tied to libc. However such option is broken at least in the gcc compiler provided in Alpine Linux, as the system include path (ie: /usr/include) takes precedence over the gcc private include path: #include <...> search starts here: /usr/include /usr/lib/gcc/x86_64-alpine-linux-musl/10.2.1/include And the headers in /usr/include are exclusively 64bit. Since -ffreestanding is currently broken on at least that distro, and for resilience against future compilers also having the option broken provide a set of stand alone 32bit headers required for the firmware build.
