Kernel build error

[James David Lyons]

I'm have trouble building the latest stabe kernel linux-5.2.9 on Debian
10 ppc

 uname -r
4.16.0-1-powerpc64


 CC      kernel/iomem.o
  CC      kernel/rseq.o
  AR      kernel/built-in.a
make[2]: *** [debian/rules:6: build] Error 2
dpkg-buildpackage: error: debian/rules build subprocess returned exit
status 2
make[1]: *** [scripts/package/Makefile:75: deb-pkg] Error 2
make: *** [Makefile:1422: deb-pkg] Error 2

I'm not sure if it's a problem with the Tabs or white spaces in the
debian/rules file or another issue. I ran into this before but don't
remember how I fixed it, or if I downloaded and oldeer kernel.
#!/usr/bin/make -f

srctree ?= .

build:
        $(MAKE) KERNELRELEASE=5.2.9
ARCH=powerpc        KBUILD_BUILD_VERSION=1 -f $(srctree)/Makefile

binary-arch:
        $(MAKE) KERNELRELEASE=5.2.9
ARCH=powerpc        KBUILD_BUILD_VERSION=1 -f $(srctree)/Makefile
intdeb-pkg

clean:
        rm -rf debian/*tmp debian/files
        $(MAKE) clean

binary: binary-arch

Anyone know how to fix this, or what the error means?
