PR 24627
* Add support for GNU_PROPERTY_AARCH64_FEATURE_1_PAC in ELF GNU program
properties in the AArch64 ELF linker.
-* Add --force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
+* Add -z force-bti for AArch64 to enable GNU_PROPERTY_AARCH64_FEATURE_1_BTI
on output while warning about missing GNU_PROPERTY_AARCH64_FEATURE_1_BTI
on inputs and use PLTs protected with BTI.
-* Add --pac-plt for AArch64 to pick PAC enabled PLTs.
+* Add -z pac-plt for AArch64 to pick PAC enabled PLTs.
