BUT x86_64 ARCH can build and run correctly.

[equation314]

Run make A=apps/c/helloworld clean_c before switching architecture.

[chyyuu]

The right building way:

make A=apps/c/helloworld ARCH=riscv64 clean
make A=apps/c/helloworld ARCH=riscv64 run

OR

make A=apps/c/helloworld ARCH=aarch64 clean
make A=apps/c/helloworld ARCH=aarch64 run

Then everything is OK!
