Provide os.arch platform name mapping for Linux s390x and zarch_64 #1388

Provide complete information about the problem

1. Version of JNA and related jars

jna-platform-5.9.0.jar

2. Version and vendor of the java virtual machine

SAPJVM 8 on linux s390x

3. Operating system

Linux s390x (issue is independent of distro, test run was on SLES)

4. System architecture (CPU type, bitness of the JVM)

s390x also known as zarch_64 (64bit)

5. Complete description of the problem

The SAPJVM8 JDK8 port on linux s390x unfortunately has system property os.arch == zArch_64 and not s390x.
This leads to an UnsatisfiedLinkError when running the Renaissance Java benchmark.
Probably adding a architecture name mapping might help to solve the issue , see

static String getCanonicalArchitecture(String arch, int platform) {
    arch = arch.toLowerCase().trim();
    if ("zarch_64".equals(arch)) {
        arch = "s390x";
    }

6. Steps to reproduce

run the renaissance benchmark on Linux s390x, sub benchmark db-shootout
sapjvm_8/bin/java -jar renaissance-gpl-0.13.0-4-g2755c79.jar db-shootout

java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/linux-zarch_64/libjnidispatch.so) not found in resource path
