binutils: Add fixes for binutils issue 16428
"ld:i386 crashes with -static -fPIE -pie" https://bugs.launchpad.net/ubuntu/+source/binutils/+bug/1266492 This adds in two upstream binutils fixes to avoid the internal error triggered by the combination of -static with -pie on x86 builds. This triggers a backtrace which then triggers a bug in glibc where the process ends up hanging on some systems with broken libcs. We can't fix the libc but we can stop the internal error and hence avoid the hanging builds. (From OE-Core rev: e949f9a8fc337bd768c7e8a3fd082775a94e0ad4) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
