[PATCH] pr82625.C: Compile with -march=x86-64

[H.J. Lu]

pr82625.C has

__attribute__ ((target ("default")))
unsigned bar() {
...
}

and

__attribute__ ((target ("avx")))

unsigned bar() {
...
}

GCC generates different assembly codes on AVX512 machines when GCC is
configured with

--with-arch=native --with-cpu=native

Compile pr82625.C with -march=x86-64 so that only AVX will be enabled by
target attribute.

* g++.target/i386/pr82625.C (dg-options): Add -march=x86-64.
