[GIT PULL] Clang build fix for 7.1 #2

[Nathan Chancellor]

Hi Linus,

Please consider pulling this small fix to disable -Wattribute-alias for
clang in the few places it is already disabled for GCC, now that tip of
tree clang has implemented -Wattribute-alias as GCC has. If you would
prefer for this to wait until the next merge window given your recent
comments on the 7.1-rc5 announcement, I can resend later. Given how
simple it is coupled with just expanding what already exists, I figured
it was not unreasonable to send it as a fix now, especially since it is
showing up in our stable builds as well.

This has been in -next for several cycles in one form with no reported
issues but I updated it yesterday to avoid breaking the build for other
versions of clang-23 that do not have this flag implemented, as this can
be rough on vendored toolchains or people like myself that have to
bisect LLVM between releases and it was rather simple to do with another
pragma line.

Please let me know if there are any issues or objections.

Cheers,
Nathan
