Look at legOS makefiles. The lx file is generated from two symbolsrec
executables linked to different positions. The files are generated
with a special linker script "legOS.lds". Maybe you can do the same
with your compiler and use the makelx program, which is included in
legOS, without modifications.
Otherwise, makelx comes with source code, so you can get more
information about lx file format there.
