A comment here would help, explaining that this looks for both .rodata
and .rodata.func_name sections (when using -fdata-sections).

This could be simplified and made more readable with something like:

        for_each_sec(file, sec) {
                if (!strncmp(sec->name, ".rodata", 7) &&
                    !strstr(sec->name, ".str1.") {
                        sec->rodata = true;
                        found = true;
                }
        }
