This patch better supports mixing of power10 and non-power10 code,
as might be seen in a cpu-optimized library using ifuncs to select
functions optimized for a given cpu. Using -Wl,--no-power10-stubs
isn't that good in this situation since non-power10 notoc stubs are
slower and larger than the power10 variants, which you'd like to use
on power10 code paths.
With this change, power10 pc-relative code that makes calls marked
@notoc uses power10 stubs if stubs are necessary, and other calls use
non-power10 instructions in stubs. This will mean that if gcc is
generating code for -mcpu=power10 but with pc-rel disabled then you'll
get the older stubs even on power10 (unless you force with
-Wl,--power10-stubs). That shouldn't be too big a problem: stubs that
use r2 are reasonable. It's just the ones that set up addressing
using "mflr 12; bcl 20,31,.+4; mflr 11; mtlr 12" that should be
avoided if possible.

+linkage stubs (PLT call and long branch) using power10 instructions

+power10 notoc stubs are smaller and faster, so are preferred for
power10. @option{--power10-stubs} and @option{--no-power10-stubs}
allow you to override the linker's selection of stub instructions.
-For example, when linking a shared library that contains cpu-optimized
-versions of functions for both power9 and power10, you might use
-@option{--no-power10-stubs} so that power9 code making calls doesn't
-attempt to execute power10 instructions.
+@option{--power10-stubs=auto} allows the user to select the default
