These is a race over the installation of files into the include/ directory between:

| (cd `${PWDCMD-pwd}`/include ; \|  tar -cf - .; exit 0) | (cd /home/pokybuild/yocto-autobuilder/yocto-slave/nightly-oecore/build/build/tmp-eglibc/work/armv5te-oe-linux-gnueabi/gcc-cross-initial/4.8.2-r0/image/home/pokybuild/yocto-autobuilder/yocto-slave/nightly-oecore/build/build/tmp-eglibc/sysroots/x86_64-linux/usr/lib/armv5te-oe-linux-gnueabi.gcc-cross-initial/gcc/arm-oe-linux-gnueabi/4.8.2/include; tar xpf - )

and

| /bin/install -c -m 644 unwind.h /home/pokybuild/yocto-autobuilder/yocto-slave/nightly-oecore/build/build/tmp-eglibc/work/armv5te-oe-linux-gnueabi/gcc-cross-initial/4.8.2-r0/image/home/pokybuild/yocto-autobuilder/yocto-slave/nightly-oecore/build/build/tmp-eglibc/sysroots/x86_64-linux/usr/lib/armv5te-oe-linux-gnueabi.gcc-cross-initial/gcc/arm-oe-linux-gnueabi/4.8.2/include
| /bin/install: cannot create regular file '/home/pokybuild/yocto-autobuilder/yocto-slave/nightly-oecore/build/build/tmp-eglibc/work/armv5te-oe-linux-gnueabi/gcc-cross-initial/4.8.2-r0/image/home/pokybuild/yocto-autobuilder/yocto-slave/nightly-oecore/build/build/tmp-eglibc/sysroots/x86_64-linux/usr/lib/armv5te-oe-linux-gnueabi.gcc-cross-initial/gcc/arm-oe-linux-gnueabi/4.8.2/include/unwind.h': File exists
| make[1]: *** [install-unwind_h] Error 1

which under the right circumstances leads to the above build failure. Since we don't 
need two copies of this file and we don't use install-no-fixincludes, we can disable 
the libgcc installation.
