ls(1): Alter time portion of "long format"
One side effect of moving to the CLDR standard for locale definitions
is that abreviated months are no longer guaranteed to align. We altered
the definitions for CJK to ensure this, but we do not want to manually
adjust every locale.
The most obvious manifestation is seen with ls(1) using the long format
(-l option). Not only is the month abbreviation no longer guaranteed to
be 3 characters wide, it's not even guaranteed to be a uniform width. As
a result, the file listing may no longer line up, as seen with French:

To address both issues (misalignment and differing widths as a function
of locale), I've modified ls(1) to use valid forms of ISO 8601, an
international standard for the representation of time.
The default long format produces the last modified timestamp in the form
of YYYYMMDDTHH (Year|Month|Day|T|Hour with no spaces). This is known as
the "basic" format which includes the optional "T" concatenator. The
result is the time is represented by a single column using 1-3 characters
less than before.
ironwolf# env LANG=fr_FR.UTF-8 ls -l | head
drwxr-xr-x 2 root wheel 512 20150326T10 ariadne
drwxr-xr-x 2 root wheel 512 20150326T10 artemis

The -T option uses the extended format of ISO 8601 without the T symbol,
but with the minutes and seconds representation. The result is two
characters wider than the approach FreeBSD is taking to address the same
issue (FreeBSD is padding the month section and expanding the field by
two characters to accommodate 5-character wide month names). The output
on DragonFly looks like this:
ironwolf# env LANG=fr_FR.UTF-8 ls -lT | head
drwxr-xr-x 2 root wheel 512 2015-03-26 10:15:28 ariadne
drwxr-xr-x 2 root wheel 512 2015-03-26 10:15:28 artemis
drwxr-xr-x 3 root wheel 512 2015-09-09 19:45:04 avida
drwxr-xr-x 3 root wheel 512 2015-09-09 19:45:04 babel
drwxr-xr-x 3 root wheel 512 2015-06-15 20:38:55 bcftools
drwxr-xr-x 2 root wheel 512 2015-09-20 11:27:40 biococoa
drwxr-xr-x 2 root wheel 512 2015-03-26 10:15:28 biojava
drwxr-xr-x 3 root wheel 512 2015-03-26 10:15:28 blat
drwxr-xr-x 3 root wheel 512 2015-11-07 08:44:24 bwa
The long format no longer changes if the last modified time is within six
months (future or past), thus file times are more quickly comparable with
a quick visual scan versus switching between year and hours:seconds.

GCC 5.0 is screaming about sh potentially getting clobbered by longjmp.
I don't know how to fix this and the WARNS system doesn't cover
-Wclobbered so I'm turning -Werror off forcibly until somebody else can
fix it. The error messages are:
