If NO_ARCH is set then check that no FreeBSD elf(5) files are in $STAGEDIR.
If an elf(5) file is bundles as part of the package, but is not meant to be
run directly (i.e. the elf(5) file is a payload, and not compiled) then
those files can be added to NO_ARCH_IGNORE to avoid the check from failing,
Changes to ports:
- Ports that have NO_ARCH set, but actually compile files have had NO_ARCH
removed.
- Ports that have elf(5) payloads have had those files added to
NO_ARCH_IGNORE.
- R-cran ports that do not set USES=cran:compiles have NO_ARCH set,

bitmapped vectors of booleans (no NAs), coercion from and to logicals,
integers and integer subscripts; fast boolean operators and fast
summary statistics. With 'bit' vectors you can store true binary
booleans {FALSE,TRUE} at the expense of 1 bit only, on a 32 bit
architecture this means factor 32 less RAM and ~ factor 32 more
speed on boolean operations. Due to overhead of R calls, actual
speed gain depends on the size of the vector: expect gains for
vectors of size > 10000 elements. Even for one-time boolean operations
it can pay-off to convert to bit, the pay-off is obvious, when such
components are used more than once. Reading from and writing to bit
is approximately as fast as accessing standard logicals - mostly
due to R's time for memory allocation. The package allows to work
with pre-allocated memory for return values by calling .Call()
directly: when evaluating the speed of C-access with pre-allocated
vector memory, coping from bit to logical requires only 70% of the
time for copying from logical to logical; and copying from logical
to bit comes at a performance penalty of 150%. the package now
contains further classes for representing logical selections:
'bitwhich' for very skewed selections and 'ri' for selecting ranges
of values for chunked processing. All three index classes can be
used for subsetting 'ff' objects (ff-2.1-0 and higher).
