1. elf2flt.ld 2. elf2flt.c (elf2flt tool) 3. binfmt_flat.c (in kernel)

elf2flt.c (around line 1300)

ld-elf2flt -- A linker replacement that implements a -elf2flt option for the
linker and runs elf2flt automatically for you. It auto
detects PIC/non-PIC code and adjusts its option accordingly.
It uses the environment variable FLTFLAGS when running
elf2flt. It runs /.../m68k-elf-ld.real to do the actual
linking.
