#     kconfig: split util.c out of parser.y
#     
#     util.c exists both in scripts/kconfig/ and scripts/kconfig/lxdialog.
#     
#     Prior to commit 54b8ae66ae1a ("kbuild: change *FLAGS_<basetarget>.o
#     to take the path relative to $(obj)"), Kbuild could not pass different
#     flags to source files with the same basename. Now that this issue
#     was solved, you can split util.c out of parser.y and compile them
#     independently of each other.
