 # BFD ld doesn't create multiple PT_LOADs as usual when an unknown section
 # exists. Using an implicit linker script to make it fold that section in
 # .data.rel.ro makes it create multiple PT_LOADs. That implicit linker
 # script however makes gold misbehave, first because it doesn't like that
 # the linker script is given after crtbegin.o, and even past that, replaces
 # the default section rules with those from the script instead of
 # supplementing them. Which leads to a lib with a huge load of sections.
