修复 macOS 10.14（Mojave）上的构建问题（Tom Lane）

\n

调整 configure 向 CPPFLAGS 添加 -isysroot 开关；没有它，PL/Perl 和 PL/Tcl 在 macOS 10.14 上无法配置或构建。所用的具体 sysroot 可以在配置或构建时通过在 configure 或 make 的参数中设置 PG_SYSROOT 变量来覆盖。

\n

现在建议与 Perl 相关的扩展在其编译器标志中写 $(perl_includespec) 而不是 -I$(perl_archlibexp)/CORE。后者在大多数平台上继续有效，但在最近的 macOS 上不行。

\n

此外，在最近的 macOS 版本上构建 PL/Tcl 应该不再需要手动指定 --with-tclconfig。

However, this was never safe for comparison functions that directly return the result of memcmp(), strcmp(), etc, as POSIX doesn't place any such restriction on those functions. At least some recent versions of memcmp() can return INT_MIN, causing incorrect sort ordering. Hence, we've removed this restriction.
