Probably the easiest thing is to just alter the function lpx_print_sol
(or lpx_print_ips or lpx_print_mip), located in file glplpx8a.c.  You
can adjust it to make the output exactly the way you want it.  I think
what you're concerned with is on line 1319 (for GLPK 4.4).

Alternatively, you could use the API to write your own program to
read/create and solve your instances and then write the solution however
you would like.  That would take a little more work but would allow you
to make other customizations as well.
