If an output section is loaded into an implicitly set LMARegion, we need to reserve space for it. Otherwise, the following output sections will use invalid region counters in their computation of offsets and assign bogus addresses.
The rules for assigning implicit LMARegions are documented here: https://sourceware.org/binutils/docs-2.20/ld/Output-Section-LMA.html

Newer versions of ld.bfd have more complicated rules (https://sourceware.org/binutils/docs-2.30/ld/Output-Section-LMA.html#Output-Section-LMA)
