As a first step, try replacing SIZEOF_HEADERS in your script with a fixed
constant.  Choose a value somewhat larger than the current header size - 
you seem to have already discovered what this is :-)

If this still gives linker errors, you will need to set up your own
program headers.  Have a look at "Node: PHDRS" in the ld info
documentation.  "readelf -l" will let you look at existing file headers.
