mmo.c: Fix ld testsuite regression "objcopy executable (pr25662)".
* mmo.c (mmo_scan): Create .text section only when needed, not
from the start.
For the test-case at hand, the .data section is created and output
first by the linker, but the mmo input-reader mmo_scan always creates
a .text section. Since sections are output in the order in which
they're created, it's output first, breaking the assumption that
obcopy without options (or with -p) creates output identical to its
input. The point of creating it at the top of mmo_scan is a trivial
default assignment for the current section variable "sec". Instead we
now defer the default, creating it only when needed and sec is NULL.
