-Subject: [PATCH] riscv/linux: Don't add -latomic with -pthread
-
-Now that we have support for inline subword atomic operations, it is no
-longer necessary to link against libatomic. This also fixes testsuite
-failures because the framework does not properly set up the linker flags
-for finding libatomic.
-The use of atomic operations is also independent of the use of libpthread.

-gcc/
- * config/riscv/linux.h (LIB_SPEC): Don't redefine.
