gdbserver seems to have grown a dependency on libiconv

Hi,

I'm just looking at adding gdb 15 to crosstool-ng. One configuration
that's having problems is xtensa-fsf-linux-uclibc.

[ERROR]    configure: error: could not find libiconv (required for
host xtensa-fsf-linux-uclibc)[ERROR]    make[2]: *** [Makefile:10924:
configure-gdbserver] Error 1
[ERROR]    make[2]: *** Waiting for unfinished jobs....

I don't think it's anything to do with the specific architecture but
it just happens this configuration doesn't end up building libiconv as
a dependency for any other part of the toolchain.

Is libiconv actually a requirement for gdbserver or is this something
that has leaked through now that gdb and gdbserver share a lot of
infrastructure?

Thanks,
Chris
