I am seeing this unused parameter 'opts' error when building for this
configuration:
Build: arm-none-linux-gnueabihf
Host: arm-none-linux-gnueabihf
Target: arm-none-linux-gnueabihf
In function 'void arm_option_restore(gcc_options*, gcc_options*,
cl_target_option*)':
/src/gcc/gcc/config/arm/arm.c:3042:41: error: unused parameter 'opts'
[-Werror=unused-parameter]

Hi!
The following patch on top of the
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/553801.html
patch fixes the gcc.target/arm/lto/pr96939_* test in certain ARM
configurations.
As said in the above mentioned patch, the generic code takes care of
saving/restoring TargetVariables or Target Save options, so this just
arranges for the generic code to save those instead of needing the
arm backend to do it manually.
Bootstrapped/regtested on armv7hl-linux-gnueabi, ok for trunk?

* config/arm/arm.opt (x_arm_arch_string, x_arm_cpu_string,
x_arm_tune_string): Remove TargetSave entries.
(march=, mcpu=, mtune=): Add Save keyword.
* config/arm/arm.c (arm_option_save): Remove.
(TARGET_OPTION_SAVE): Don't redefine.
(arm_option_restore): Don't restore x_arm_*_string here.
