    gcc-cross: default linker hash style to sysv
    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.
    This is limited to cross, to retain ease of use for SDKs.
