Starting off with 2.2.0 doesn't make any difference. If I do this

0 3>root at pye-dev-01:/usr/local/src/fpc/fpcbuild# make "GDB_V603=1" 
OPT="-O- -g" all

I get this

/usr/local/src/fpc/fpcbuild-2.2.2/fpcsrc/compiler/ppc1 -Ur -Ur -Xs -O2 
-n -Fi../inc -Fi../sparc -Fi../unix -Fisparc -FE. 
-FU/usr/local/src/fpc/fpcbuild-2.2.2/fpcsrc/rtl/units/sparc-linux -O- -g 
-dsparc -dRELEASE ../objpas/math.pp
Fatal: Compilation aborted

I can confirm that ppc1 has been recently built so should have -g etc. 
If I do this

# cd /usr/local/src/fpc/fpcbuild-2.2.2/fpcsrc/rtl/linux
# gdb /usr/local/src/fpc/fpcbuild-2.2.2/fpcsrc/compiler/ppc1
(gdb) set args -Ur -Ur -Xs -O2 -n -Fi../inc -Fi../sparc -Fi../unix 
-Fisparc -FE. 
-FU/usr/local/src/fpc/fpcbuild-2.2.2/fpcsrc/rtl/units/sparc-linux -O- -g 
-dsparc -dRELEASE ../objpas/math.pp
(gdb) tty /dev/pts/5
(gdb) run

where /dev/pts/5 is another Konsole session running bash as root, I get 
this:

Hope I got that right.
