literal_prefix directive allows you to override the default
literal section names, which are derived from the names of the sections
where the literals are defined.
.begin literal_prefix [name] .end literal_prefix
For literals defined within the delimited region, the literal section names are derived from the name argument instead of the name of the current section. The rules used to derive the literal section names do not change. See literal. If the name argument is omitted, the literal sections revert to the defaults. This directive has no effect when using the `--text-section-literals' option (see Command Line Options).
