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.

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