[petsc-users] Can not configure PETSc-master with clang-3.9

[Satish Balay]

Thats weird.

>From what I can recall - some tools (like pgi compilers) need this -
but the xcode compilers do not.

Basically xcode clang can pick up includes from the xcode specific
location - but other tools look for includes in /usr/incldue

And 'xcode-select --install' adds the /usr/include etc links.
