Makefile* Problem Adding C23 stdbits Functions

[Joel Sherrill]

Hi

I am in the process of adding FreeBSD's implementation of stdbit.h
functions to newlib. I am attaching just the changes to libc/Makefile.inc
and the new libc/stdbit/Makefile.inc. I ran autoreconf from newlib. The
versions are:

autoconf (GNU Autoconf) 2.69
automake (GNU automake) 1.16.5

When I ran autoreconf, there were no warnings or errors but when I build,
there is this error:

===========================
config.status:1583: cd .       && sed -e '/# am--include-marker/d' Makefile
        | make -f - am--depfiles
make[2]: Entering directory
'/home/joel/test-gcc/b-sparc-rtems7-newlib/sparc-rtems7/newlib'
/tmp/GmySNETs:14839: *** mixed implicit and normal rules.  Stop.
make[2]: Leaving directory
'/home/joel/test-gcc/b-sparc-rtems7-newlib/sparc-rtems7/newlib'
config.status:1588: $? = 2
config.status:1592: error: in
`/home/joel/test-gcc/b-sparc-rtems7-newlib/sparc-rtems7/newlib':
config.status:1594: error: Something went wrong bootstrapping makefile
fragments
    for automatic dependency tracking.  If GNU make was not used, consider
    re-running the configure script with MAKE="gmake" (or whatever is
    necessary).  You can also try re-running configure with the
    '--disable-dependency-tracking' option to at least be able to build
    the package (albeit without support for automatic dependency tracking).
See `config.log' for more details
===========================

The above is from the config.log file which has the information on the
failure.

I thought this would be simple given the new-ish Makefile.inc system.

Any suggestions?
