cross compile OpenJDK-9+158 minimal variant failed when link libjvm.so

[Bob Vandette]

I just cloned the latest http://hg.openjdk.java.net/jdk9/dev
and was able to successfully build OpenJDK with the minimalvm.

Here’s my configure script.

/export/users/bobv/jdk9devopenonly/configure --enable-option-checking=fatal --build=x86_64-unknown-linux-gnu --host=arm-linux-gnueabihf --target=arm-linux-gnueabihf --with-jdk-variant=normal  --with-jvm-variants=minimal  --with-x=/java/embedded/buildtools/gcc/linux/arm/gcc-linaro-arm-linux-gnueabihf-raspbian-2012.09-20120921_linux/arm-linux-gnueabihf/libc/usr/X11R6-PI  --with-alsa=/java/embedded/buildtools/gcc/linux/arm/gcc-linaro-arm-linux-gnueabihf-raspbian-2012.09-20120921_linux/arm-linux-gnueabihf/libc/usr/include/alsa   --with-abi-profile=arm-vfp-sflt  --with-cups-include=/java/devtools/share/cups/include/  --with-devkit=/java/embedded/buildtools/gcc/linux/arm/arm-linaro-4.7  --with-build-devkit=/java/devtools/linux/devkit/gcc4.9.2-OEL6.4  --with-debug-level=release  --with-freetype-lib=/java/embedded/buildtools/freetype-2.6.2/build_linux-arm//lib  --with-freetype-include=/java/embedded/buildtools/freetype-2.6.2/build_linux-arm//include/freetype2  --disable-warnings-as-errors

Note: I had to apply this fix in order to build arm-vfp-sflt ABI profile.  This fix will be in the mainline soon.
