Prune BFD warnings for unknown GNU properties

Browse source 
When glibc is enabled with the new GNU_PROPERTY_X86_XXX bits:

https://groups.google.com/forum/#!topic/x86-64-abi/-D05GQ3kWrA

BFD will issue an unknown GNU property warning like

warning: tmpdir/ld1: unsupported GNU_PROPERTY_TYPE (5) type: 0xc0010001

and ignore such GNU properties.  This patch adds prune_warnings_extra to
prune such warnings on release branches and updates prune_warnings to
call prune_warnings_extra.
