Title:
  add -fno-strict-aliasing for more architectures in R3.16 src/ca/legacy
  Makefiles

Status in EPICS Base:
  Fix Released
Status in EPICS Base 3.16 series:
  Fix Released
Status in EPICS Base 7.0 series:
  Fix Released

Bug description:
  In addition to the existing
  USR_CXXFLAGS_Linux = -fno-strict-aliasing
  USR_CXXFLAGS_RTEMS = -fno-strict-aliasing

  add this line to src/ca/legacy/gdd/Makefile:
  USR_CXXFLAGS_vxWorks = -fno-strict-aliasing

  Add all three lines to src/ca/legacy/pcas/build/Makefile.

  The vxWorks 6 compilers between 6.2 and 6.7 all print warnings about
  broken strict aliasing rules and all understand that flag. The vxWorks
  5 compiler does not understand the flag but 3.16 does not build with
  vxWorks 5 anyway.
