   Hello,
thanks for the reply.
My program code is ok, and also lpc1768.o and the cortexm3_start code is ok.
But code from system.o is wrong.
And thanks to Michael Ring I now can be more consise:

  arm-none-eabi-readelf -A lpc1768.o
Attribute Section: aeabi
File Attributes
   Tag_CPU_name: "7-M"
   Tag_CPU_arch: v7
   Tag_CPU_arch_profile: Microcontroller
   Tag_THUMB_ISA_use: Thumb-2

arm-none-eabi-readelf -A system.o
Attribute Section: aeabi
File Attributes
   Tag_CPU_arch: v5TE
   Tag_ARM_ISA_use: Yes
   Tag_THUMB_ISA_use: Thumb-1

So why is system.o generated in the wrong version?
I think that I did everything as I said.
I will do the compiler starting from scratch again, just to be sure.
I now know where to look for.
