[OE-core] [PATCH 2/3] gcc-4.6: Use --with-linker-hash-style configure option

Sun Aug 21 23:07:18 UTC 2011
Depending upon what hash style is in use this uses
the right flag for setting the hash style type. This
fixes the QA errors about missing GNU hash style reported
in gcc-runtime build particularly libgcc
