If xcrun prints warnings or errors to stderr while determining the SDK
version, they become part of the SDK version string. This then leads to
a qmake error.
Intentionally ignore stderr so that it is not treated as part of the SDK
version.

Also catches some more variants of SDK mismatch, such as Xcode not
being installed at all, or the SDK missing.

We want to inform the user when they have upgraded their Xcode version
and hence have a new SDK version, which requires a complete rebuild.
Explicit changes to the Xcode selection (be it via xcode-select or
$DEVELOPER_DIR) do not affect the existing build directory, so we must
record the Xcode selection inside the build to avoid false triggering.

Otherwise the SDK upgrade (or downgrade) may subtly and silently affect
the resulting binary, or if it results in build breaks, the user won't
know why.
We limit it to applications for now, as that's the point where it's
most important to catch the SDK upgrade, but technically we should
also do this for intermediate libraries. Doing it for everything
will likely incur a performance cost, so we skip that for now.
