@opindex rdynamic
Pass the flag @option{-export-dynamic} to the ELF linker, on targets
that support it. This instructs the linker to add all symbols, not
only used ones, to the dynamic symbol table. This option is needed
for some uses of @code{dlopen} or to allow obtaining backtraces
from within a program.

@opindex s
Remove all symbol table and relocation information from the executable.
