For me, it bombed with

I could see quite a lot going on in /usr/include/errno.h ->
bits/errno.h -> linux/errno.h but I thought I might as well get
everything to use the available linux/errno.h with
sed -i -e 's%\(errno\.h\)%linux/\1%' sunrpc/*.c
but it now fails with
auth_unix.c: In function 'authunix_create_default':
auth_unix.c:194:11: error: 'errno' undeclared (first use in this

I can see the following in /usr/include/errno.h
#ifndef _ERRNO_H
/* The includer defined __need_Emath if he wants only the
* definitions
of EDOM and ERANGE, and not everything else. */
#ifndef __need_Emath

#endif

#include <bits/errno.h>
#undef __need_Emath
#ifdef _ERRNO_H

trigger
a -Wstrict-prototypes warning. */

#endif
but in bits/errno.h I can see

I suppose this is only needed by the invocations of cross-rpcgen in
glibc, which on x86_64 start with
CPP='x86_64-lfs-linux-gnu-gcc -E -x c-header'
/mnt/lfs/building/glibc-build/sunrpc/cross-rpcgen -Y ../scripts -h
rpcsvc/bootparam_prot.x -o
/mnt/lfs/building/glibc-build/sunrpc/rpcsvc/bootparam_prot.T
/bin/sh ../scripts/move-if-change
/mnt/lfs/building/glibc-build/sunrpc/xbootparam_prot.T
/mnt/lfs/building/glibc-build/sunrpc/xbootparam_prot.c
but I've no idea how to define code for the errno function now that
the host's glibc appears to be unavailable.
