Hi,An error has been reported in crosstool-ng for building strace with mips-*-linux-musl host. The same problem has been previously reported for OpenEmbedded; I verified the same patch works in crosstool-ng (after regenerating configure).
I am not the original developer of the patch [1], but it appears to be signed-off-by properly. Note that the patch claims it has been submitted upstream, but I couldn't find it in strace's mailing list archives.

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.
