+Subject: [musl] [PATCH] elf.h: add typedefs for Elf*_Relr
+
+Add typedefs for Elf32_Relr and Elf64_Relr as a follow-up to commit
+d32dadd60efb (ldso: support DT_RELR relative relocation format)
+
+---
+This fixes build of iproute2 with elfutils 0.190, which assumes that
+Elf*_Relr are typedef'ed when SHT_RELR is defined.
