exactly and that is built by the RTEMS :

rtems@rtems-dev:~/MVME6100_WORK/rtems/6/make/custom$ more beatnik.cfg
include $(RTEMS_ROOT)/make/custom/default.cfg
CPU_DEFINES = -I$(exec_prefix)/$(RTEMS_BSP)/lib/include
CPU_CFLAGS = -mcpu=7400
CFLAGS_OPTIMIZE_V = -O2 -g -fdata-sections -ffunction-sections
LDFLAGS = -B$(exec_prefix)/$(RTEMS_BSP)/lib -qrtems -Wl,--gc-sections

in share/rtems6/make/compilers/gcc-target-default.cfg
...
# NOTE: CPU_DEFINES should probably be merged with CPU_CFLAGS
CPPFLAGS += $(CPU_DEFINES) $(CPU_CFLAGS) $(DEFINES) $(XCPPFLAGS)

Which gets called in CONFIG.Common.RTEMS by inlude $(CONFIG.CC)

…
# Pick up the RTEMS tool/path definitions from the RTEMS BSP directory.
include $(RTEMS_BASE)/$(GNU_TARGET)$(RTEMS_VERSION)/$(RTEMS_BSP)/Makefile.inc
include $(RTEMS_CUSTOM)
include $(CONFIG.CC)

I have not yet managed to do the “shifting to the end”.  I first renamed link.h in the rtems/beatnik/include.

And could build anything with it:

I'll have a look at the -isystem. Thanks Heinz
