commit 9a66b3b0349e0a158bb4940b668a5cbc7c245762

    Simplify endianness checks
    
    Linux can be built with too many types of C run-time library and it's
    not reasonable to have to enumerate all of them, especially since at
    least one of them (MUSL) goes out of its way to not be easily
    detectable.
    
    Instead, leverage autoconf better for Linux/BSD to detect either
    <endian.h> or <sys/endian.h> directly.

    Sys headers should not be included directly
    
    There's usually a top-level header which then includes the sys/
    descendent.
