[PATCH] config: fix AM_ICONV for in-tree libiconv

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.)

Once these two patches are merged in to each tree, I will follow with
patches to regenerate the various configure scripts and a few other
minor corresponding changes.
