On some Windows systems, antivirus, endpoint-security or DLP/encryption
software intercepts short-lived toolchain processes and strips their
stdout when the build captures it through a pipe, while the same command
prints its output normally when run by hand. The tool exits successfully
but returns nothing, and each build step that reads toolchain output then
failed with a different, cryptic error far from the real cause:
- CMake configuration aborted with "Unknown arguments specified" in
components/xtensa/project_include.cmake, or "check_expected_tool_version
invoked with incorrect arguments" in components/esp_common.
- ldgen turned the empty objdump output into an opaque pyparsing
"Expected 'In archive'" traceback.
- idf_tools.py silently reported the compiler/debugger version as
"unknown", sending users into a fruitless reinstall loop.
Detect the empty result at each consumer and fail (or warn) with an
actionable message that names the likely cause and the remedy:
- tools/cmake/compiler_query.cmake: new __compiler_query() helper runs a
compiler query and fails with a clear error on empty or failed output.
It is a standalone module included by both the cmakev1 and cmakev2
utilities, since the esp_common and xtensa project_include.cmake that
call it are shared by both build systems. The xtensa if() arguments are
now quoted so an empty result no longer collapses into a parse error.
- tools/ldgen/ldgen.py: _run_objdump() rejects empty objdump output, and
non-empty-but-unparsable section info is caught and re-raised as a clear
LdGenFailure instead of a raw pyparsing traceback.
- tools/idf_tools.py: empty version output now warns with the cause and
returns UNKNOWN_VERSION instead of silently reporting "unknown".

Nix will create a new derivation in the store for python packages,
which leads to mismatch between the system prefixes, invalidating a
widely used check for being in a virtual environment.
This adds a Nix-specific fix for virtualenv detection.
Closes https://github.com/espressif/esp-idf/pull/14435
Currently, when the venv is installed or updated, we attempt to
automatically update pip and setuptools within the venv. Unfortunately,
the setuptools package is installed or updated without adhering to the
constraints file, which restricts the setuptools version due to
https://github.com/pypa/setuptools/issues/4480. Resolve this issue by
applying the constraints file to the installation and update of both pip
and setuptools.

Warn if IDF_PYTHON_ENV_PATH set to a suspicious path with
different ESP-IDF version and/or Python version.
Fail if the virtual environment was created for a different ESP-IDF
version.
