 My normal build, reproduction for git master:
 ./configure --enable-nonfree --enable-cuda --enable-libnpp --extra-
 cflags=-I/opt/cuda/include --extra-ldflags=-L/opt/cuda/lib64
 make -j4

 All is fine in the previous commit
 (1349de10b22d6c8643bec43eced296ec2a126671).

 Attached config.log for the failed build.

 Failure output during linking:

Comment:

 The configure line does not look useful but the priority is hard to
 disagree with...
