Borislav Petkov 03bf0f163d x86/build: Disable CET instrumentation in the kernel for 32-bit too
[ Upstream commit 256b92af784d5043eeb7d559b6d5963dcc2ecb10 ]

Commit

  20bf2b378729 ("x86/build: Disable CET instrumentation in the kernel")

disabled CET instrumentation which gets added by default by the Ubuntu
gcc9 and 10 by default, but did that only for 64-bit builds. It would
still fail when building a 32-bit target. So disable CET for all x86
builds.
