+Subject: [PATCH 07/10] use <asm/sgidefs.h>
+
+Build fix for MIPS with musl libc
+
+The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
+but not by musl. Regardless of the libc, the kernel headers provide
+<asm/sgidefs.h> which provides the same definitions, so use that
+instead.

Currently building gdb for MIPS musl fails because it's trying to include <sgidefs.h> which is provided by glibc and uClibc, but not by musl. However, the kernel headers provide <asm/sgidefs.h> which has the same definitions, so we can use that one instead. Backporting a patch that has been sent upstream.
