commit c199fd785d18121ffd0ba5758e23a42ba2984e11

    perf tools: Expose quiet/verbose variables in Makefile.perf
    
    The variables to make builds silent/verbose live inside
    tools/build/Makefile.build. Move those variables to the top-level
    Makefile.perf to be generally available.
    
    Committer testing:
    
    See the SYSCALL lines, now they are consistent with the other
    operations in other lines:
