Actually opencv is a cmake target, you cannot (easily) change that !
Cmake is the alternative to the autotools used by opencv.

The problem is that BR generate the output/toolchainfile.cmake that
describe the toolchain you're currently using,
But unfortunately, this file is wrong, it does not match your current
toolchain; it cerlainly one of your previous configuration.

So, removing output/toolchainfile.cmake will make BR regenerate it
according to the current configuration during the next build.
Then, when cmake will be called to configure opencv, the
toolchainfile.cmake passed as argument will be correct.
