This seems to work fine (added to target-supports.exp), except that
you'd use them in your example as just "c" and "c++".

# Return 1 if the language for the compiler under test is C.

proc check_effective_target_c { } {
  global tool
  if [string match $tool "gcc"] {
    return 1
  }
  return 0
}

# Return 1 if the language for the compiler under test is C++.

proc check_effective_target_c++ { } {
  global tool
  if [string match $tool "g++"] {
    return 1
  }
  return 0
}
