Ok, I've got it. I had to add -lgcc also for some more targets in Makefile.am:
if NETBOOT_SUPPORT
-pre_stage2_exec_LDADD = ../netboot/libdrivers.a
+pre_stage2_exec_LDADD = ../netboot/libdrivers.a -lgcc
+else
+pre_stage2_exec_LDADD = -lgcc
endif

This compiles and works, but only with stage2. When using stage1_5, grub hangs
on boot with
GRUB loading stage1.5
and blinking cursor. Is the multidevice patch also necessary for single
devices? I've omitted this patch, since my root-fs (with /boot) lies on a
single partition.
