Call dpkg-deb directly instead of using the dpkg front-end, and pass it
any options found in the new KBUILD_DEBOPTS variable. With "-Zxz", this
allows compressing packages with xz instead of gzip, which provides very
significant space savings (x86-64 allmodconfig):
gzip xz
linux-firmware-image.deb 1.2M 903K
linux-headers.deb 7.3M 5.1M
linux-image.deb 197M 118M
linux-libc-dev.deb 855K 653K
