New Revision: 279908
URL: https://svnweb.freebsd.org/changeset/base/279908
Log:
Provide automatic cross-binutils path if no BINUTILS_BOOTSTRAP
The in-tree binutils does not support arm64, so will not work for the
forthcoming FreeBSD arm64 port. BROKEN_OPTIONS will include
BINUTILS_BOOTSTRAP, so provide a default CROSS_BINUTILS_PREFIX for this
case.
