[patch, testsuite] check for UTF-32 target wide charset support in gdb.base/wchar.exp

- Authentication-results: sourceware.org; auth=none
This patch is related to the one I posted yesterday to make
with_target_charset do something reasonable in the absence of ICONV support:
https://sourceware.org/ml/gdb-patches/2015-09/msg00357.html
If GDB is configured without ICONV support, the target wide charset
defaults to "ISO-8859-1" (which isn't even a wide charset), and all the
wide strings in this test print as gibberish. Otherwise, GDB seems to
think the default is "auto; currently UTF-32", so let's make the
dependency on UTF-32 explicit here and bail out if it's not available.
OK to commit?
