The transposition nolto -> notlo is confusing and it makes the long
name even harder to read than it already is - I kept reading it as
"not lo" until I realized it was a simple typo.
Fixes: 5269b24605b1 (Silence warning in LTO mode on VxWorks)
lto-plugin/
* lto-plugin.c: Fix -linker-output-auto-notlo-rel ->
-linker-output-auto-nolto-rel typo.
(process_option): Adjust accordingly, accepting both old and
new spelling.
gcc/
* config/vxworks.h (LTO_PLUGIN_SPEC): Adapt to corrected
spelling of -linker-output-auto-nolto-rel.

v2: still accept -linker-output-auto-notlo-rel in the plugin.
