If there's support for symbol aliases, have to 'dg-skip-if' -- unless
there's a way to disable this support, which there is for GCC/nvptx:
'-mno-alias'.  OK to push the attached
"nvptx: Specify '-mno-alias' for 'gcc.dg/pr60797.c' [PR60797, PR104957]"?

Subject: [PATCH] nvptx: Specify '-mno-alias' for 'gcc.dg/pr60797.c' [PR60797,
 PR104957]

2014 Subversion r209299 (Git commit 8330537b5b58bd0532a0a49f9cbd59bf526a7847)
"Fix PR60797" added this test case, which we now amend so that it's able to
test its thing also in '--target=nvptx-none' configurations with symbol alias
support enabled (..., and test nvptx '-mno-alias').

	PR middle-end/60797
	PR target/104957
	gcc/testsuite/
	* gcc.dg/pr60797.c: For nvptx, specify '-mno-alias'.
