Thomas De Schampheleire be084204eb Config.in files: add missing dependencies to toolchain option comments
When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:

config BR2_PACKAGE_A
	depends on BR2_B
	depends on BR2_LARGEFILE
	depends on BR2_WCHAR

comment "A needs a toolchain w/ largefile, wchar"
	depends on !BR2_LARGEFILE || !BR2_WCHAR

This comment should actually be:

comment "A needs a toolchain w/ largefile, wchar"
	depends on BR2_B
	depends on !BR2_LARGEFILE || !BR2_WCHAR

or if possible (typically when B is a package config option declared in that
same Config.in file):

if BR2_B

comment "A needs a toolchain w/ largefile, wchar"
	depends on !BR2_LARGEFILE || !BR2_WCHAR

[other config options depending on B]

endif

Otherwise, the comment would be visible even though the other dependencies
are not met.

This patch adds such missing dependencies, and changes existing such
dependencies from
  depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
  depends on BR2_BASE_DEP
  depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

help
Dstat, written in Python, is a versatile replacement for vmstat,
iostat, netstat and ifstat. Dstat overcomes some of their limitations
and adds some extra features, more counters and flexibility. Dstat is
handy for monitoring systems during performance tuning tests,
benchmarks or troubleshooting.
Dstat allows you to view all of your system resources in real-time,
you can e.g. compare disk utilization in combination with interrupts
from your IDE controller, or compare the network bandwidth numbers
directly with the disk throughput (in the same interval).
Note that to get proper output, your terminal size should be known by
the termios subsystem. This can be done by running the 'resize'
utility of busybox.
