Compatibility Concerns

#6276 - Remove -nostartfiles and -nodefaultlibs from individual board Make.defs.

#6256 - Remove ARCHWARNINGS = -Wall -Wstrict-prototypes -Wshadow -Wundef and ARCHWARNINGSXX = -Wall -Wshadow -Wundef and then remove ARCHWARNINGS and ARCHWARNINGSXX from CFLAGS and CXXFLAGS.

#5897 - Remove -fno-exceptions -fcheck-new from ARCHCFLAGS and ARCHCXXFLAGS and change ARCHCFLAGS = to ARCHCFLAGS += and ARCHCXXFLAGS = to ARCHCXXFLAGS +=. C++ exceptions are now managed centrally by Kconfig options CONFIG_CXX_EXCEPTION and CONFIG_CXX_RTTI.

#6144 - Remove from each board:

ifeq ($(CONFIG_DEBUG_SYMBOLS),y)
ARCHOPTIMIZATION = -g
endif

and

ifeq ($(CONFIG_DEBUG_SYMBOLS),y)
LDFLAGS += -g
endif

as these are now managed centrally by Kconfig option CONFIG_DEBUG_SYMBOLS.

#6155 - Remove from each board:

ifneq ($(CONFIG_DEBUG_NOOPT),y)
ARCHOPTIMIZATION += $(MAXOPTIMIZATION) -fno-strict-aliasing
endif

as these are now managed centrally by Kconfig options CONFIG_DEBUG_OPTLEVEL and CONFIG_DEBUG_FULLOPT.
