Changed the conditionals for setting defaults for compilers. Instead
of checking for SPEC being set, each variable (CC, CXX etc) are
checked with the origin function and only set if they have the default
value. For on standard variables, ?= assignment is used. Made sure all
executables set in this way have ?= so they are controlable from
configure. Moved include SPEC away from compiler makefiles and added
them to generated makefile instead.
