* aclocal/enable-rtemsbsp.m4: Split out RTEMS_ENV_RTEMSBSP,
	RTEMS_ENV_RTEMSCPU.
	* aclocal/env-rtemsbsp.m4: New file for RTEMS_ENV_RTEMSBSP, add
	special treatment for GCC_SPECS.
	* aclocal/env-rtemscpu.m4: New file for RTEMS_ENV_RTEMSCPU, add
	special treatment for GCC_SPECS.
	* aclocal/bsp-enable-arg.m4: New file, introduce RTEMS_BSP_ARG_ENABLE.
	* aclocal/prog-cc.m4: Add AC_PROG_CPP, use build_os in GCCSED hack.
	* automake/compile.am: New treatment of CPP, GCCSPECS, use `..`
	instead of $(shell ..) for LIBC_LIB*.
