During an exp-run for llvm 14 (see bug 261742), it turned out that sysutils/dtc
fails to build with clang 14:

libfdt/fdt_rw.c:438:6: error: use of bitwise '|' with boolean operands
[-Werror,-Wbitwise-instead-of-logical]
        if (can_assume(LIBFDT_ORDER) |
            ^~~~~~~~~~~~~~~~~~~~~~~~~~
                                     ||

#define can_assume(_assume)     can_assume_(ASSUME_ ## _assume)
                                ^
libfdt/fdt_rw.c:438:6: note: cast one or both operands to int to silence this

                                ^
1 error generated.

This looks like a bug in dtc, it should quite obviously use a logical ||
instead of a bitwise | here. I will attach at patch to this bug.
