./configure --toolchain=msvc --enable-cross-compile --arch=x86_64 --extra-ldflags="-static-libgcc" --extra-cflags=-I/usr/include --extra-ldflags=-L/usr/lib
cl.exe is unable to create an executable file.
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.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
