    newlib: merge acconfig.h changes into newlib.hin
    
    The acconfig.h header was used to run autoheader and then manually
    sync the output into newlib.hin.  Based on how the files have fallen
    out of sync (with newlib.hin having many more templates), this has
    not been run in a long time, and attempts to do so now would break
    newlib.hin.
    
    Further, if you try to run autoheader now, it will automatically
    replace _newlib_version.hin since it's the first entry in the call
    to AC_CONFIG_HEADERS.
    
    So let's throw away acconfig.h entirely.  It only had 2 slightly
    better comments, and the rest were either worse, missing, or stale.
    This has the side benefit of avoiding autoheader warning about the
    deprecated use of acconfig.h since newer autoconf only wants macro
    calls in configure.ac.
