--- Comment #1 from Fangrui Song <i at maskray.me> ---
In GNU ld, -z notext/-z text/unspecified are a tri-state. For -z
notext/unspecified, the dynamic tags DT_TEXTREL and DF_TEXTREL are added on
demand. If unspecified and GNU ld is configured with
--enable-textrel-check=warning, a warning will be issued.

LLD has two states and adds DT_TEXTREL and DF_TEXTREL if -z notext is
specified.

The LLD handling is simpler and incompatible with old GNU ld (but more
compatible with new binutils behavior), but with the evolution of toolchain
when -z notext is phased out, this difference should not be a problem.
