+# - There is already --with-libiconv-prefix but we can't use it, it specifies
+# the build-time location of libiconv files.
+# - The program we need to find is iconv, which comes with glibc. The user
+# doesn't necessarily have libiconv installed. Therefore naming this
+# --with-libiconv-foo feels wrong.
+# - We want the path to be relocatable, but GDB_AC_DEFINE_RELOCATABLE is
+# defined to work on directories not files (though it really doesn't know
+# the difference).
+# - Calling this --with-iconv-prefix is perceived to cause too much confusion
+# with --with-libiconv-prefix.
+# Putting these together is why the option name is --with-iconv-bin.
