sparcv9: Disable -Wuninitialized warnings breaking bootstrap [PR92002]
sparcv9 bootstrap has been broken for 1 1/2 years now by spurious
-Wuninitialized warnings:

Before we ship yet another release with this issue, I suggest to at
least include a workaround of demoting them to warnings.
Tested on sparcv9-sun-solaris2.11.
