This change adds a check for binutils 2.25 or higher after 8265783. The change 8265783 introduced on linux x86_64 a minimum requirement for binutils : "Minimum required would be binutils 2.25 where AVX512 support was added for Skylake."  (see https://bugs.openjdk.java.net/browse/JDK-8265783 )
I adjusted the existing check that already checked the binutils version by looking at the linker output (we do not look at the assembler version and it seems to me we do not really invoke the assembler directly, just indirectly via gcc).
