configure: Use per-language unknown-warnings-flags

Browse Source 
E.g. when CC is clang, the unknown warnings flags
are -Werror=unused-command-line-argument and
-Werror=unknown-warning-option. These flags are currently
also used for testing the C++ and ObjC compilers, yet
g++ does not recognize these flags and errors out because
of them, so that the tests fail and the parentheses,
switch etc. warnings are not disabled for C++.

Fix this by using per-language flags.
