[committed][testsuite, nvptx] Fix string matching in gcc.dg/pr87314-1.c

[Tom de Vries]

Hi,

with nvptx we run into:
...
FAIL: gcc.dg/pr87314-1.c scan-assembler hellooo
...

The required string is part of the assembly, just in a different format than
expected:
...
        .const .align 1 .u8 $LC0[12] =
          { 104, 101, 108, 108, 111, 111, 111, 111, 98, 121, 101, 0 };
...

Fix this by adding an nvptx-specific scan-assembler directive.

Tested on nvptx and x86_64.

Committed to trunk.

Thanks,
- Tom
