[Lldb-commits] [lldb] [lldb] Add RISCV for Makefile.rules (PR #124758)

[via lldb-commits]

https://github.com/kper created https://github.com/llvm/llvm-project/pull/124758

As discussed with @DavidSpickett in discord. Running the test runner caused the following issue:

```
gmake: Entering directory '/home/kper/oss/llvm-project/build/lldb-test-build.noindex/functionalities/thread/concurrent_events/TestConcurrentSignalWatch.test'
/home/kper/oss/llvm-project/build/bin/clang++  -std=c++11 -g -O0  -mriscv -I/home/kper/oss/llvm-project/lldb/packages/Python/lldbsuite/test/make/../../../../..//include -I/home/kper/oss/llvm-project/build/tools/lldb/include -I/home/kper/oss/llvm-project/lldb/test/API/functionalities/thread/concurrent_events -I/home/kper/oss/llvm-project/lldb/packages/Python/lldbsuite/test/make -include /home/kper/oss/llvm-project/lldb/packages/Python/lldbsuite/test/make/test_common.h -fno-limit-debug-info      --driver-mode=g++ -MT main.o -MD -MP -MF main.d -c -o main.o /home/kper/oss/llvm-project/lldb/test/API/functionalities/thread/concurrent_events/main.cpp
clang++: error: unknown argument: '-mriscv'
gmake: *** [Makefile.rules:619: main.o] Error 1
```

By overriding the flags, we avoid the `-mriscv`.
