Autoconf build: Fix the invalid test for '-Wno-deprecated-copy' flag
(shamelessly stolen from c26db650a1, which was for cmake build)
The original test was always successfull, even if the flag was invalid.
But checking for '-Wdeprecated-copy' instead yields to error if the
warning does not exist. Existent warning for 'deprecated-copy' implies
that 'no-deprecated-copy' also exist.
