Comment (by infinoid):

 I just ran into this here, so I can confirm.

 Debian bullseye recently updated its (nonfree) cuda packages to version
 11.0, and this caused ffmpeg's configure script to stop detecting nvcc.

 I changed compute_30 and sm_30 to compute_35 and sm_35 in the configure
 script, as @mliradelc suggests.  This built successfully, and the
 resulting binary is able to encode video with h264_nvenc successfully.

 Note, the configure script hides the following warning from nvcc:

 `nvcc warning : The 'compute_35', 'compute_37', 'compute_50', 'sm_35',
 'sm_37' and 'sm_50' architectures are deprecated, and may be removed in a
 future release (Use -Wno-deprecated-gpu-targets to suppress warning).`

 So they work for now, but won't work for much longer.

 My system info:
 amd64
 linux-image-5.8.18  5.8.18-1
 nvidia-cuda-toolkit 11.0.3-2
 nvidia-kernel-dkms  450.80.02-1
 `41:00.0 VGA compatible controller [0300]: NVIDIA Corporation TU104
 [GeForce RTX 2080 SUPER] [10de:1e81] (rev a1)`
