#     kbuild: replace $(if A,A,B) with $(or A,B)
#     
#     $(or ...) is available since GNU Make 3.81, and useful to shorten the
#     code in some places.
#     
#     Covert as follows:
#     
#       $(if A,A,B)  -->  $(or A,B)
#     
#     This patch also converts:
#     
#       $(if A, A, B) --> $(or A, B)
#     
#     Strictly speaking, the latter is not an equivalent conversion because
#     GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
#     expands to " A", while $(or A, B) expands to "A".
#     
#     Anyway, preceding spaces are not significant in the code hunks I touched.
