build: [g++-5.4.0] suppress boost warnings

Problem: sched fails to compile with gcc-5.4.0
and boost-1.53 due to excessive compiler warnings
that are treated as errors.

Suppress the following warnings completely:
  unused-local-typedefs
  deprecated-declarations
  unused-variable

Don't suppress this warning since it may identify a real
problem at resource_gen_spec.cpp:26, but for now make it
non-fatal:
  maybe-uninitialized
