Original description:
This is the second in a series of patches to make a build with an
in-tree GNU libiconv work as designed.
Currently GDB is the only toolchain component which actually uses an
in-tree libiconv. This patch modifies the common AM_ICONV to use an
in-tree libiconv when present and not already provided by libc.
(GDB's workaround uses an in-tree libiconv even when libc provides
iconv(3); I'm not sure when or why that would be desirable.)

When using options such as --localize-symbol, --globalize-symbol, etc,
along with the --wildcard option, prefixing a symbol name with '!'
should provide non-matching behaviour, as example the following example
is given in the manual:
--wildcard --weaken-symbol !foo --weaken-symbol fo*
which should weaken all symbols matching the pattern 'fo*', but not the
symbol 'foo'.
However, this currently does not work, the current logic will waken all
symbols matching the pattern 'fo*' AND all symbols that are not 'foo'.
The symbol 'foo' is covered by the first condition, and so is weakened,
while, other symbols, for example 'bar' will match the second condition,
and so be weakened.
This patch adjusts the logic so that a pattern prefixed with '!'
specifically DOES NOT apply the relevant change to any matching symbols,
instead of applying the change to all non-matching symbols. So this:
--weaken-symbol !foo
will ensure that the symbol 'foo' is not weakened, but says nothing
about symbols that are not 'foo'. As a result, a pattern prefixed with
'!' now only makes sense when used alongside a more wide ranging
wildcard pattern.
This change should make the wildcard matching feature more useful, with
no overall loss of functionality. The example given in the manual,
weaken all symbols matching 'fo*' except 'foo' can now be achieved, but
so too can more complex examples, such as weaken all symbols matching
'fo*' except 'foo', 'foa', and 'fob', like this:
--wildcard --weaken-symbol !foo \
--weaken-symbol !foa \
--weaken-symbol !fob \
--weaken-symbol fo*
Under the previous scheme, something as symbols as, weaken all symbols
except 'foo' could have been achieved with this:
--weaken-symbol !foo
however, this will no longer work. To achieve the same result under the
new scheme this is now required:
--weaken-symbol !foo --weaken-symbol *
