Assume that we can use LWARX hint flags and the LWSYNC instruction on any PPC machine. The check on the assembler's behavior was only needed for Apple's old assembler, which is no longer of interest now that we've de-supported all PPC-era versions of macOS (thanks to them not having clock_gettime()). Also, given an up-to-date assembler these instructions work even on Apple's old hardware. It seems quite unlikely that anyone would be interested in running current Postgres on PPC hardware that's so old as to not have these instructions. Hence, rip out associated configure test and manual configuration options, and just use the modernized instructions all the time. Also, update atomics/arch-ppc.h to use these instructions as well. (It was already using LWSYNC unconditionally in another place, providing further proof that nobody is using PG on hardware old enough to have a problem with that.)

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
