Alexey Brodkin cb2e8c5d9c binutils: now depends on wchar
binutils starting at least from 2.23 when build for target require
uClibc configured with UCLIBC_HAS_WCHAR otherwise:

libtool: link: [...] -o as-new [...]
read.o: In function `read_symbol_name':
read.c:(.text+0x3634): undefined reference to `mbstowcs'
collect2: error: ld returned 1 exit status

because "mbstowcs" is not available in the C library.

Even though we're not yet using 2.23.2 as the default version, we will
probably do it in the near future, so this commit doesn't bother with
making the wchar dependency version-specific, and applies it to the
binutils package as a whole.

Fixes bug #6218

[Thomas:
 - more details in the commit log.
 - add comment about the wchar dependency
 - propagate the dependency to dropwatch (and fix a mistake in the
   architecture dependencies of the comment)
 - propagate the dependency to oprofile.]

OProfile is a system-wide profiler for Linux systems,
capable of profiling all running code at low overhead.
OProfile is released under the GNU GPL.
It consists of a kernel driver and a daemon for collecting
sample data, and several post-profiling tools for turning
data into information.
OProfile leverages the hardware performance counters of the
CPU to enable profiling of a wide variety of interesting
statistics, which can also be used for basic time-spent
profiling. All code is profiled: hardware and software
interrupt handlers, kernel modules, the kernel, shared
libraries, and applications.
