* configure.ac: Pass CFLAGS to cpukit configure.
	* aclocal/rtems-flags.m4: Remove (Unused).
	* aclocal/prog-ccas.m4: Remove $(GCCSPECS).
	* aclocal/env-rtemsbsp.m4:
	Comment out CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V, CPU_CFLAGS.
	* aclocal/prog-cc.m4: Don't invoke _RTEMS_FLAGS to set up
	RTEMS_CFLAGS.
	* automake/compile.am: AM_CFLAGS = RTEMS_CFLAGS. Add AM_CXXFLAGS.
	Remove CPPFLAGS, CFLAGS, CPU_CFLAGS, CFLAGS_OPTIMIZE, ASFLAGS.

## -------------------------------------------------------------------------
## NOTE: This file is rather immature and has to be considered to be
## almost experimental.
##
## Expect frequent changes -- It deserves to be cleaned up :(
## -------------------------------------------------------------------------
## The section below is based on make/compilers/gcc-target-default.cfg
## used in former versions of RTEMS.
##
## Set up the flags for the toolchains:
##
## We are considering 3 different building schemes here:
## * Using gcc's being able to accept -specs (aka gcc-2.8 building scheme)
## * Using gcc's not being able to accept -specs (aka gcc-2.7.2 building
## scheme)
## * Using third party toolchains (aka non-gcc building scheme)
##
## Automake conditionals in use:
## RTEMS_USE_GCC .. if we are using GCC
## NOTES:
## * The gcc-2.8 building scheme is the nominal building scheme and
## is actively supported.
## * The non-gcc building scheme requires manually setting up environment
## variables and is hardly tested at all
## CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V are the values we
## would want the corresponding macros to be set to.
##
## CFLAGS_OPTIMIZE, CFLAGS_DEBUG are set by the
## 'VARIANT=<OPTIMIZE|DEBUG>' targets to their _V values.
