Maybe I can try a full system rebuild with -mlra...

Maybe we can set it as the release target of GCC 15.

-mlra has been set to default since it was added (2014).
So, It is ok for us to remove it.

Then let's just remove it (maybe after GCC 14 release).

    MIPS: Remove -m(no-)lra option

    PR target/113955
    The `-mlra` option was introduced in 2014 for MIPS, and was set to
    default since then.  It's time for us to drop no-lra support by
    dropping -m(no-)lra options.

    gcc:
            * config/mips/mips.cc(mips_option_override):
            Drop mips_lra_flag variable;
            (mips_lra_p): Removed.
            (TARGET_LRA_P): Remove definition here to use the default one.
            * config/mips/mips.md(*mul_acc_si, *mul_acc_si_r3900, *mul_sub_si):
            Drop mips_lra_flag variable.
            * config/mips/mips.opt(-mlra): Removed.
            * config/mips/mips.opt.urls(mlra): Removed.
