dwarf2read: Allow SEC_ALLOC sections to be located at address 0.
GDB already allows statically initialized variables, located in
SEC_LOAD sections, to be placed at address 0. This change allows
uninitialized variables (which are in SEC_ALLOC sections) to be placed
address 0 as well.
gdb/ChangeLog:
* dwarf2read.c (dwarf2_locate_sections): Allow has_section_at_zero
to be set for SEC_ALLOC sections too.
