Base them on the existing `x86_64` specs. Update the centos
base image from centos 6 to centos 7 to get aarch64 support.
The resulting binaries require GLIBC 2.17.

Some static analysis tools incorrectly identify this constructor
as leaving _has_value in an undefined state. Explicitly call the
default constructor to force _has_value to false.
Sphinx has deprecated `sphinx.util.pycompat.htmlescape` and
`sphinx.builders.qthelp.QtHelpBuilder`. We only import these as part of
a monkey-patch to work around a bug in versions of sphinx before 1.7.2,
so make that code path conditional. The imports are not deprecated on
the versions where we need them.
62d7acc6 added arguments to Flex when regenerating
cmCommandArgumentLexer, but this was not reflected in
Utilities/Scripts/regenerate-lexers.bash. Update the script with
the proper arguments.
Since these commits:
* commit ab2276e6b9 (Utilities/Release: remove old macOS release script,
2020-09-16)
* commit 7670ba8b0a (Utilities/Release: Drop win{32,64} scripts in favor
of docker build, 2020-05-05, v3.18.0-rc1~203^2)
* commit 689fdbfc61 (Utilities/Release: Drop linux64 script in favor of
docker build, 2019-08-27, v3.16.0-rc1~184^2)
several scripts we once used for producing release binaries for
distribution on `cmake.org` are no longer needed.
#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
In commit 714ce72882 (bootstrap: Make libuv available during bootstrap,
2017-09-13, v3.10.0-rc1~106^2) we modified libuv to use POSIX interfaces
during bootstrap. However, some code still expects `TARGET_OS_IPHONE`
to be defined on Apple platforms to either `0` or `1`. In order to
offer this, include `<TargetConditionals.h>` on Apple platforms even
when bootstrapping.
