Thanks, I comiled this way :

make clean buildbase installbase "OPT=-gl -Xs- -O-" CROSSINSTALL=1 
OS_TARGET=embedded CPU_TARGET=arm SUBARCH=armv7

That gives this :

 > gdb --args ../../compiler/ppcrossarm -Cparmv7m @rtl.cfg -Ur 
-Tembedded -Parm -XParm-embedded- -Xr -Ur -Xs -O2 -n -Fi../inc -Fi../arm 
-FE. -FU/home/koenraad/Documenten/fpc-20130123/rtl/units/arm-embedded 
-darm -dRELEASE  -Us -Sg system.pp
