Hi Simon,

Thanks for the try. Please see the comment below.

It is not related to cross-compiling. Actually, I have tried to
simplify the test matrix, which limits the compilation only on x86_64.
And I got the similar error [1]

The workflow control file is [2], which clips out all arches except
x86_64.  But I can successfully build it on the Fedora system with the
following bash script, which is based on the github's build log.  So
maybe it is a bug with the compiling tools?

kexec_tools_dir="./"

mkdir $kexec_tools_dir/_build \
         $kexec_tools_dir/_build/sub \
         $kexec_tools_dir/_inst \
         $kexec_tools_dir/_dest
chmod a-w $kexec_tools_dir
test -d $kexec_tools_dir/_build
INSTALL_BASE=$(cd $kexec_tools_dir/_inst && pwd | sed -e
's,^[^:\\/]:[\\/],/,') &&\
        DESTDIR="$kexec_tools_dir/_dest" && \
        cd $kexec_tools_dir/_build/sub && \
                ../../configure \
                 \
                --srcdir=../.. --prefix="$INSTALL_BASE" && \
        make  -j8
