[PATCH] x86/Kconfig: Allow X86_X32_ABI with llvm-objcopy in some cases

From: Alex Xu (Hello71)
Date: Fri Jul 01 2022 - 17:04:56 EST


According to the comment and commit message, there are issues compiling
with IBT and/or compressed debug sections. Therefore, the condition
should be restricted to when those are enabled.
