The configure check always fail with clang:

conftest.c:5:58: error: expected string literal as argument of 'alias' attribute
    5 | extern __typeof (__foo) foo __attribute__ ((weak, alias (__foo)));
      |                                                          ^
conftest.c:6:58: error: expected string literal as argument of 'alias' attribute
    6 | extern __typeof (__foo) bar __attribute__ ((weak, alias (foo)));
      |                                                          ^
