Dear Maintainer,

Now ldc does not support riscv64 either upstream or Debian. Fortunately,
The Arch linux has porting the riscv64 support[0] for ldc. And I try to
build ldc on Debian riscv64 arch with their patch. Despite the twists
and turns of the process, in the end the build was successfully. I also
got the support from upstream[1].

The patch attached is to add support for riscv64 on Debian. I have
tested it on my riscv machines.

The mirror issue in the patch here is I have to disable check D_COMPILER_FLAGS
from CMake. I am not sure if this is the inappropriate
DADDITIONAL_DEFAULT_LDC_SWITCHES flag I added in the d/rules. Anyway, it
works.

The next version of ldc from upstream will have better support for
riscv64 as upstream said. I think this is good start to add support riscv64
build about D language packages if apply the change on Debian.

Please let me know if there is any issues.

Dear Maintainer,

Now ldc has been built on riscv64 without any code change. So can we
enable riscv64 support on build target on next upload?
