Peter Eisentraut 41a2b56ae8 PL/Tcl: Don't link with -lc explicitly 
It has been reported that PL/Tcl built on macOS with GCC >=11 crashes.
The reason is that there is a hash_search() function in the operating
system's libraries, and that ends up being called instead of the one
in postgres.  This has something to do with how the linker resolves
references between the various possibilities it has been given, and
somehow something changed that it is now picking that one in this
configuration.

We found that removing the -lc from the link command line fixes this
problem.  The -lc was introduced a long time ago in commit
e3909672f1, and we think the reasons
might be obsolete, so we decided that we'll try to just remove it and
see if any problems arise.

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/.
