[oe] [meta-java] gcc 4.8 and openjdk-8

[Jacopo Malvestio]

Hello All,

I've created a .bbappend file with:

CFLAGS_remove = "-fno-lifetime-dse"
CXXFLAGS_remove = "-fno-lifetime-dse"

but the do_configure step fail, bitbake -v openjdk-8 log:

| configure: Current directory is /home/jacopo/yjp/poky/build/tmp/work/x86_64-linux/openjdk-8-native/72b05-r0/build.
| configure: Since this is not the source root, configure will output the configuration here
| configure: (as opposed to creating a configuration in <src_root>/build/<conf-name>).
| configure: However, this directory is not empty. This is not allowed, since it could

| configure: (or create a new empty directory and cd to it).
| configure: error: Will not continue creating configuration in /home/jacopo/yjp/poky/build/tmp/work/x86_64-linux/openjdk-8-native/72b05-r0/build

I'm running on ubuntu 14.04 with gcc4.8 and openjdk 1.8, i don't think it's a side effect of the gcc6 patch,  but in your opinion, i forgot something?

thank you
