3d9c649158 ls: don't output any colors with TERM=dumb
The TERM variable is usually set to "dumb" to indicate that the terminal
does not support any ANSI escape sequences. Presently, ls does not honor
this variable and outputs colors anyhow which results in unreadable
output, unless the user explicitly disables colors using `ls
--color=never`. The rational behind this change is that ls should "just
work" by default, even on dumb terminals.

For this reason, this patch adds a check which additionally consults the
TERM variable before printing any colors. This is analogous to the
existing check for ensuring that standard output is a tty. As such,
colors can still be forced with `--color=force`, even if TERM is set to
dumb.

79c92dbd70 touch: switch to using utimensat() and futimens()
This patch changes the functions used to update timestamps in touch.

Before, utimes() and lutimes() were used, which had certain
disadvantages.
They are unable to handle nanosecond timestamps, and implementations of
certain features like -a and -m require running stat() in a loop.

Almost all implementations of utimes() and lutimes() are wrappers for
utimensat(), this is the case for glibc, ulibc and musl libc.

7ec254467c touch: remove unneeded GETOPT32 defines
Long options handling (getopt32 vs getopt32long) is done in libbb.h, no need to
care here of the same logic. This cleans the code a bit.

Also, --no-create was grouped as a SUSv3 option, where as the short -c was not.
Even if it is part of SUS, leave it out as was the short option.

v2: Fix for disabled ENABLE_LONG_OPTS. getopt32long does not like
  IF_FEATURE_xxx() style conditionals... :/

e880c9c100 echo: do not assume that free() leaves errno unmodified
musl libc's mallocng free() may modify errno if kernel does not support
MADV_FREE which causes echo to echo with error when it shouldn't.

Future versions of POSIX[1] will require that free() leaves errno
unmodified but til then, do not rely free() implementation.

Should fix downstream issues:
