#     kbuild: deb-pkg: use default string when variable is unset or null
#     
#     ${DEBFULLNAME-${user}} falls back to ${user} when DEBFULLNAME is unset.
#     It is more reasonable to do so when DEBFULLNAME is unset or null.
#     
#     Otherwise, the command:
#     
#       $ DEBFULLNAME= make deb-pkg
#     
#     will leave the name field blank.
#     
#     The same applies to KBUILD_BUILD_USER and KBUILD_BUILD_HOST.
