[committed][testsuite] Check target alias in builtin-has-attribute-3.c

[Tom de Vries]

Hi,

When running test-case c-c++-common/builtin-has-attribute-3.c on nvptx, I get:
...
FAIL: c-c++-common/builtin-has-attribute-3.c  -Wc++-compat \
  (test for excess errors)
Excess errors:
src/gcc/testsuite/c-c++-common/builtin-has-attribute-3.c:33:33: error: \
  alias definitions not supported in this configuration
...

Fix this by adding -DSKIP_ALIAS to the compilation options for effective
target ! alias.

Tested on nvptx.

Committed to trunk.

Thanks,
- Tom
