xcompile: More updates on ARM64 Erratum flags

I tried to handle the checking for the config flag internal to xcompile,
    but the config flags don't appear to have been loaded into the
    environment by make at that point.

This does update the if to check if the flag is even set before putting
    anything into .xcompile though.  If the LDFLAG isn't set, there's no
    point in appending anything.

Also removes the LP version of the erratum config flag, which was a
    copy/paste mistake from $(CONFIG_LP_COMPILER_GCC).
