Initially I used two files because supposed it worth to check/show that we can have at least 2 different .rela.text sections
and able to concatenate it correctly with fixup of values to output section.

For SHT_REL[A] sections the are currently 3 logical branches when them are met:
 -relocatable, common way and --emit-relocs. 
And that is the only testcase which has at least 2 RELA sections we have atm with -emit-relocs.
