[OE-core] [master][PATCH] gcc-cross{, -canadian}: remove --with-linker-hash-style

[Christopher Larson]

From: Christopher Larson <chris_larson at mentor.com>

We explicitly set the hash style to gnu in our LDFLAGS. Setting the default to
this in the toolchain, while convenient, actually hides bugs, as a failure to
obey LDFLAGS isn't noticed. By removing this, it's not dissimilar to how we
poison the sysroot -- rather than relying on the default, notice right away if
somoeone isn't obeying the needed flags.

This will result in a failure to obey LDFLAGS causing a GNU_HASH QA failure,
which is what's often seen with external toolchains. This brings us all on the
same page, and makes sure a failure to obey LDFLAGS is seen early.
