[Yang Shino]

Summary of the bug:
ffmpeg failed to config on release|arm64 with MSVC on Windows. This issue can be reproduced from master revision c523724. Could you please help take a look at this? Thank you!
Repro steps:

1. Open a VS 2019 x64 prompt
2. set VSCMD_SKIP_SENDTELEMETRY=1 & "C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\Common7\Tools\VsDevCmd.bat" -host_arch=amd64 -arch=arm64
3. git clone ​https://github.com/FFmpeg/FFmpeg F:\gitP\FFmpeg/FFmpeg
4. git -C "F:\gitP\FFmpeg\FFmpeg" reset --hard c523724
5. cd F:\gitP\FFmpeg\FFmpeg\..\
6. set FFMPEG_SRC_PATH=F:\gitP\FFmpeg\FFmpeg
7. set FFMPEG_FATE_PATH=../fate-suite/
8. set path=F:\gitP\FFmpeg\FFmpeg\..\tools;%PATH%
9. set MSYS2_PATH_TYPE=inherit
10. .\tools\msys32\usr\bin\sh.exe --login -i -c "/F/gitP/ffmpeg/tools/build.sh"

Error message:
cl.exe is unable to create an executable file.
If cl.exe is a cross-compiler, use the --enable-cross-compile option.
Only do this if you know what cross compiling means.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
​ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
Failed to configure!
