Subject: [PATCH] xtensa: don't produce FDPIC output with fdpic toolchain
Date: Fri, 12 Jan 2024 22:34:44 -0800 [thread overview]
Message-ID: <20240113063444.4189388-1-jcmvbkbc@gmail.com> (raw)
The kernel doesn't use features of the FDPIC toolchain, disable FDPIC
code generation when using such toolchain and select ordinary ELF linker
emulation.
