Details

Description:

RISCV64 requires libatomic for pthreads, but this lib is not provided by the current RISCV compiler packages.
So all programs that require -pthread fail to link.

For at least some programs, replacing -pthread with -lpthread seems to be sufficient.

Additional info:
* riscv64-linux-gnu-gcc 8.2.0-1
* riscv64-linux-gnu-binutils 2.31.1-1
* riscv64-linux-gnu-glibc 2.27-1
* riscv64-linux-gnu-linux-api-headers 4.16-1

Steps to reproduce:

$ echo "int main() {}" > main.c
$ riscv64-linux-gnu-gcc -pthread empty.c
/usr/lib/gcc/riscv64-linux-gnu/8.2.0/../../../../riscv64-linux-gnu/bin/ld: cannot find -latomic
collect2: error: ld returned 1 exit status
