#     Makefile: use -z pack-relative-relocs
#     
#     Commit 27f2a4db76e8 ("Makefile: fix GDB warning with CONFIG_RELR")
#     added --use-android-relr-tags to fix a GDB warning
#     
#     BFD: /android0/linux-next/vmlinux: unknown type [0x13] section `.relr.dyn'
#     
#     The GDB warning has been fixed in version 11.2.
#     
#     The DT_ANDROID_RELR tag was deprecated since DT_RELR was standardized.
#     Thus, --use-android-relr-tags should be removed. While making the
#     change, try -z pack-relative-relocs, which is supported since LLD 15.
#     Keep supporting --pack-dyn-relocs=relr as well for older LLD versions.
#     There is no indication of obsolescence for --pack-dyn-relocs=relr.
#     
#     As of today, GNU ld supports the latter option for x86 and powerpc64
#     ports and has no intention to support --pack-dyn-relocs=relr. In the
#     absence of the glibc symbol version GLIBC_ABI_DT_RELR,
#     --pack-dyn-relocs=relr and -z pack-relative-relocs are identical in
#     ld.lld.
#     
#     GNU ld and newer versions of LLD report warnings (instead of errors) for
#     unknown -z options. Only errors lead to non-zero exit codes. Therefore,
#     we should test --pack-dyn-relocs=relr before testing
#     -z pack-relative-relocs.
