## This checks that:
## 1) Address of _etext is the first location after the last read-only loadable segment.
## 2) Address of _edata points to the end of the last non SHT_NOBITS section.
##    That is how gold/bfd do. At the same time specs says: "If the address of _edata is
##    greater than the address of _etext, the address of _end is same as the address
##    of _edata." (https://docs.oracle.com/cd/E53394_01/html/E54766/u-etext-3c.html).
## 3) Address of _end is different from _edata because of 2.
## 4) Addresses of _edata == edata, _end == end and _etext == etext.
