[Buildroot] make failure trying to buildroot for raspberry pi 3 using external toolchain

[John]

I'm trying to perform a make using the latest buildroot version (2021.08.1)
but it fails at the point of trying to build libgpg-error.  I'm running on a
Ubuntu 20.04 VM under 

Windows 10 VBox.  Here's what I believe is the pertinent output info:

 

configure: WARNING: unrecognized options: --disable-gtk-doc,
--disable-gtk-doc-html, --disable-doc, --disable-docs,
--disable-documentation, --with-xmlto, --with-fop, --enable-ipv6,
--disable-nls

 

        GPGME v1.15.1 has been configured as follows:

 

        Revision:          bb988077  (48024)

        Platform:          arm-buildroot-linux-gnueabihf

 

        UI Server:         yes

        FD Passing:        yes

 

        Language bindings: cl cpp

 

        Mismatches between the target platform and the to

        be used libraries have been been detected for:

          libgpg-error

        Please check above for warning messages.

End of output log:

Perhaps I have a configuration error but I don't know what it is.

Please help.
