gcc-4.6: Use --with-linker-hash-style configure option
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 (From OE-Core rev: f8edd9b872bcf14da037bd0b501ccc8c6fcc79bf) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
