Many thanks to contributors who fixed openjdk build issues introduced by gcc v5 and for maintainers for pushing the updates.
However one problem remains: openjdk build fails in openjdk/jdk/make/java/nio due to -static compiler flag being used in conjunction with -pthread giving error
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lc

I fixed this by removing -static flag from Makefile. Not sure of this was the right thing to do (so I didn't submit patch) but it worked for me. 
I added the following to the an openjdk bbappend and it fixed the build and resulting jre is running OK.

do_configure_append() {
	gcc -v 2>&1 | grep 5\..
	if [ "$?" == "0" ]; then
		sed -i s/-static// ${B}/openjdk/jdk/make/java/nio/Makefile
	fi
}

Regards,

Henry Bruce

its not clear how the -static flag can cause this. may be its using CC
for LD or wise versa ?

why this check for gcc ?

Not clear to me either, but if you create a simple file, say test.c

int main()
{
  return 0;
}

and compile with gcc test.c -pthread -static
it fails as follows with gcc v5 
/usr/bin/ld: cannot find -lpthread
/usr/bin/ld: cannot find -lc

but compiles OK with earlier versions of gcc.

It only fails with gcc v5, so if it's not broken, don't fix it...

isn’t this gcc on your build host ?

Yes, it is the gcc on my build host. 
The openjdk recipe causes this specific makefile to build with
${CC_FOR_BUILD} which is "gcc" not ${CC}.

I think it's not related to the gcc version, I met this error in my host with
gcc 4.4.7, it's because the static library libpthread.a is not installed.

The "-static" option was added by the patch icedtea-jdk-build-nio-gensor-genuc-gensc-static.patch
which I think is inappropriate and no evidence or comments explaining why it needs static builds,
so I sent a patch to drop the patch.

Thanks,
Jackie
