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.
