/* GNU/Linux binaries do not need the extended PT_DYNAMIC section.
glibc's dynamic linker has traditionally derived the number of
tags from the p_filesz field, and sometimes allocates stack
arrays of that size. An overly-big PT_DYNAMIC segment can
be actively harmful in such cases. Making PT_DYNAMIC contain
other sections can also make life hard for the prelinker,
which might move one of the other sections to a different
PT_LOAD segment. */
