Bug#924713: opencv: please disable gdcm2 support and enable tbb support on riscv64

[Aurelien Jarno]

Source: opencv
Version: 3.2.0+dfsg-6
Severity: normal
Tags: patch

Usertags: riscv64

Hi,

opencv is currently not buildable on riscv64 as gdcm2 is not available.
It indirectly requires llvm support (through castxml), which won't be
available before llvm9. In the meantime, would it be possible to disable
gdcm2 support as already done on some other architecture? On the other
way I realized that tbb support is available on riscv64 and thus can be
enabled.

The attached patch does the above changes. Could you please include it
in the next upload?

Thanks,
Aurelien
