Support creating debuginfo for clr_debug_fuse

[gtkramer]

This should be done in a separate pipeline running on an agent different than the build agent. Do not want debuginfo generation to be in the critical path of the build because it is optional for non-developers who are just running or hosting applications.

Start with the script from https://github.com/clearlinux/clr-debug-info in scripts/clr_debug_prepare along with the following code, replacing/removing undefined variables as necessary:

RAW=${DEBUGINFODIR}.raw

refresh_clr-debug-info() {
	local "${@}"
	TYPE=projects
	PROJ=clr-debug-info
	if [[ -d "${BUILDDIR}/${TYPE}/${PROJ}" ]] ; then
        	sudo rm -rf "${BUILDDIR}/${TYPE}/${PROJ}/"
        fi
        git clone "${GITHOST}:${TYPE}/${PROJ}" "${BUILDDIR}/${TYPE}/${PROJ}"
        
	PROJDIR=${REPO_BASE_DIR}/${PROJ}
        pushd ${PROJDIR}

        # clr-debug-info HEAD moves forward at will, but releases are tagged 
        # with one, two , or three didgets if it ever reaches release 100.
        TAG=$(git tag -l | grep -E "^[0-9]{1,3}$" | sort -n | tail -1)
        git checkout ${TAG}     || error "git special checkout failed"

        autoreconf -fiv
        if [[ $? -ne 0 ]]; then
                error "autoreconf -fiv failed"
        fi
        ${PROJDIR}/configure --prefix=${BUILDDIR}/usr
        if [[ $? -ne 0 ]]; then
                error "${PROJDIR}/configure ... failed"
        fi
        make
        sudo make install
        if [[ $? -ne 0 ]]; then
                error "make install failed"
        fi

        popd
}
