Build System: Build Continues after Sub-Make Error

Discovered that the build system does not error out when individual sub-make operations fail. This behavior is undesirable, as the build will run to completion and still provide a zero exit status. For ease of triage, any failure in the build sequence should terminate immediately and provide a non-zero exit status.

Quick way to reproduce issue: build PAPI with libsde removed from src/Makefile.inc
