Subject: [PATCH] arch/sh/ add missing : in asm() statement

Due to a missing ":" in an asm() statement, the "memory" statement is
considered by gcc as input operands and not clobbers, which causes a
build failure:

In file included from ./src/internal/atomic.h:6:0,
                 from ./src/internal/pthread_impl.h:10,
                 from src/ldso/dlerror.c:4:
./arch/sh/atomic_arch.h: In function 'a_barrier':
./arch/sh/atomic_arch.h:24:44: error: expected '(' before ')' token
  __asm__ __volatile__ ("synco" : : "memory");
