m4-native, zedboard, "Please port gnulib fseeko.c to your platform"

  been away from YP for a few months, diving back in, want to build a
core-image-minimal for my zedboard, and i will first admit that i'm
using a non-approved distro (fully-updated fedora 29):

"WARNING: Host distribution "fedora-29" has not been validated with
this version of the build system; you may possibly experience
unexpected failures. It is recommended that you use a tested
distribution."

  no matter, i will live dangerously. but then things take an ugly
turn:

"WARNING: Your host glibc verson (2.28) is newer than that in
uninative (2.27). Disabling uninative so that sstate is not
corrupted."

  ok, let's see how far we get ... and that's here, trying to compile
m4-native:

| gcc   -I. -I../../m4-1.4.18/lib
-isystem/home/rpjday/oe/builds/zedboard/tmp/work/x86_64-linux/m4-native/1.4.18-r0/recipe-sysroot-native/usr/include

|   #error "Please port gnulib freadahead.c to your platform! Look at

|    #error "Please port gnulib fseeko.c to your platform! Look at the

and so on. red hat's bugzilla has an entry for just this:

https://bugzilla.redhat.com/show_bug.cgi?id=1595702

but i'm unsure (read, have no clue) how to deal with this, and i
suspect it affects more targets than just zedboard which is why i'm
asking on the general YP list.

  thoughts? is there a cheap fix for this? i'm about to dive into
debugging this, but if someone wants to make my life easy, that'd be
great.

If upgrading Yocto/poky and layers is not an option for you, then building
in a container is the typical approach.  This isolates you from any host-
distro issues, since any distro can be used in the container.

Many just set up their own with a simple Docker file, but from what I
remember the CROPS project is one common project recommended in the past. 
Here's a random starting point I found [1].

move to thud, ive confirmed it works on fedora 29 after seeing the
same issue, or ...VM with Debian / Ubuntu
