>Description:
The recent changes to NetBSD's toolchain break building the "grub" package:

cc  -O2 -I/usr/pkg/include  -Wl,-R/usr/pkg/lib -L/usr/pkg/lib -o pre_stage2.exec -nostdlib -Wl,-N -Wl,-Ttext -Wl,8200 pre_stage2_exec-asm.o pre_stage2_exec-bios.o pre_stage2_exec-boot.o pre_stage2_exec-builtins.o pre_stage2_exec-common.o pre_stage2_exec-char_io.o pre_stage2_exec-cmdline.o pre_stage2_exec-disk_io.o pre_stage2_exec-gunzip.o pre_stage2_exec-fsys_ext2fs.o pre_stage2_exec-fsys_fat.o pre_stage2_exec-fsys_ffs.o pre_stage2_exec-fsys_jfs.o pre_stage2_exec-fsys_minix.o pre_stage2_exec-fsys_reiserfs.o pre_stage2_exec-fsys_vstafs.o pre_stage2_exec-fsys_xfs.o pre_stage2_exec-hercules.o pre_stage2_exec-serial.o pre_stage2_exec-smp-imps.o pre_stage2_exec-stage2.o pre_stage2_exec-md5.o ../netboot/libdrivers.a 
pre_stage2_exec-builtins.o: In function `blocklist_func':
pre_stage2_exec-builtins.o(.text+0x220): undefined reference to `__enable_execute_stack'
pre_stage2_exec-builtins.o: In function `install_func':
pre_stage2_exec-builtins.o(.text+0x16cf): undefined reference to `__enable_execute_stack'
pre_stage2_exec-builtins.o(.text+0x16f2): undefined reference to `__enable_execute_stack'
gmake[2]: *** [pre_stage2.exec] Error 1
gmake[2]: Leaving directory `/src/NetBSD-current/pkgsrc/sysutils/grub/work/grub-0.92/stage2'

The reason is that NetBSD's compiler now emits calls to __enable_execute_stack
for nested C functions(*) which breaks standalone programs.

(*) one of the great extensions to the C language in GCC
