asm_*_offsets to define variables as constants

This change is to allow obj_int_extract to extract all integers
in the data segment. With the const keyword these variables are
forced into the .rodata segment even for zero variable value.

We had a problem before that zero valueed variables would get
assigned to BSS segment that fooled obj_int_extract to give
incorrect values.
