[petsc-users] install petsc with valgrind

[Satish Balay]

Well - its best if the .o files are not deleted..  [then you don't
have to run dsymutil]. One way to do it [if using PETSc makefiles] is:

make test RM=/bin/true

To run dsymutil - I think you need the .o files anyway - and run it as instructed below.
