#     powerpc/vmlinux.lds: Don't discard .comment
#     
#     Although the powerpc linker script mentions .comment in the DISCARD
#     section, that has never actually caused it to be discarded, because the
#     earlier ELF_DETAILS macro (previously STABS_DEBUG) explicitly includes
#     .comment.
#     
#     However commit 99cb0d917ffa ("arch: fix broken BuildID for arm64 and
#     riscv") introduced an earlier use of DISCARD as part of the RO_DATA
#     macro. With binutils < 2.36 that causes the DISCARD directives later in
#     the script to be applied earlier, causing .comment to actually be
#     discarded.
#     
#     It's confusing to explicitly include and discard .comment, and even more
#     so if the behaviour depends on the toolchain version. So don't discard
#     .comment in order to maintain the existing behaviour in all cases.
#
