    cancel valgrind build: bad shared flags
    
    The build compiles with valgrind but fails to link:
      /usr/bin/ld: /usr/lib/valgrind/libcoregrind-amd64-linux.a(libcoregrind_amd64_linux_a-m_main.o): relocation R_X86_64_32S against `vgPlain_interim_stack' can not be used when making a shared object; recompile with -fPIC
      /usr/lib/valgrind/libcoregrind-amd64-linux.a: error adding symbols: Bad value
      collect2: error: ld returned 1 exit status
    
    Adding -fPIC to LDFLAGS does not help.
    
    I think the error means that for PETSc to be built with -fPIC, then
    valgrind should also be built with -fPIC (which it is not),
    
    The -fPIC flag is generated by PETSc configuration,
    cf. config/BuildSystem/config/setCompilers.py
    
    It can be switched off with --with-pic=0, but that is incompatible
    with --with-shared-libraries.  And we want PETSc to be a shared library.
    
    Could be the only fix is to ask if valgrind can be built with -fPIC
    (bug reported Bug#800614)
    
    So we'll have to do without valgrind for now :(
