@itemx --no-copy-dt-needed-entries
This option affects the treatment of dynamic libraries referred to
by DT_NEEDED tags @emph{inside} ELF dynamic libraries mentioned on the
command line. Normally the linker will add a DT_NEEDED tag to the
command line. Normally the linker won't add a DT_NEEDED tag to the
output binary for each library mentioned in a DT_NEEDED tag in an
input dynamic library. With @option{--no-copy-dt-needed-entries}

follow it will have their DT_NEEDED entries ignored. The default
behaviour can be restored with @option{--copy-dt-needed-entries}.

This option also has an effect on the resolution of symbols in dynamic
libraries. With the default setting dynamic libraries mentioned on
the command line will be recursively searched, following their
DT_NEEDED tags to other libraries, in order to resolve symbols
required by the output binary. With
@option{--no-copy-dt-needed-entries} specified however the searching
of dynamic libraries that follow it will stop with the dynamic
library itself. No DT_NEEDED links will be traversed to resolve
