- Loop over USES twice, once to define all *_ARGS variables and once to
include Uses/*.mk. This allows all Uses/*.mk to examine arguments given
to other USES entries.
- Always define *_ARGS (possibly empty) and replace commas with spaces.
Similar for _USES_POST.
Adjust all Uses/*.mk:
- defined(u_ARGS) becomes !empty(u_ARGS)
- Eliminate helper variables like _*_ARGS=${*_ARGS:C/,/ /g}
- Some Uses/*.mk used ":" as argument separator instead of ",", but no port
used this form
- Uses/cran.mk: remove unused variable VALID_ARGS and USES+=fortran which
has no effect
- Uses/twisted.mk: simplify handling of the case where neither "build" nor
"run" arguments have been specified
