I've just attempted "configure" on s390 and here is what I get:
configure:35266: checking whether the C compiler works
configure:35288: /usr/bin/gcc -m32    -m32   conftest.c  >&5
gcc: error: unrecognized command line option '-m32'
gcc: error: unrecognized command line option '-m32'
configure:35292: $? = 1
configure:35330: result: no
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME "OpenJDK"
| #define PACKAGE_TARNAME "openjdk"
| #define PACKAGE_VERSION "jdk9"
| #define PACKAGE_STRING "OpenJDK jdk9"
| #define PACKAGE_BUGREPORT "build-dev@openjdk.java.net"
| #define PACKAGE_URL "http://openjdk.java.net";
| /* end confdefs.h.  */
| 
| int
| main ()
| {
| 
|   ;
|   return 0;
| }
configure:35335: error: in `/jdk-hs':
configure:35337: error: C compiler cannot create executables

Indeed:
<mock-chroot> sh-4.2# gcc -m32 conftest.c 
gcc: error: unrecognized command line option ‘-m32’
<mock-chroot> sh-4.2# echo $?
1
<mock-chroot> sh-4.2# gcc conftest.c
<mock-chroot> sh-4.2# echo $?
0 

This must have broken recently :( I'll take a look. As it's preventing
me to test JDK-8201495

Is there a bug for this already?

Thanks,
Severin
