Author: jhb (src,doc committer) Date: Wed Jun 20 17:42:35 2018 New Revision: 472890 URL: https://svnweb.freebsd.org/changeset/ports/472890 Log: Set OS versions to target system versions for CROSS_SYSROOT. When cross-building a package via a CROSS_SYSROOT, set OSVERSION, _OSRELEASE, and OSREL to the target OS version. OSVERSION is derived from the <sys/param.h> header in the sysroot. _OSRELEASE cannot be easily derived from a sysroot as it is a property of a kernel, so instead generate a "fake" _OSRELEASE from the OSVERSION, but use a "-CROSS" branch name that will hopefully fail in any places that make assumptions about branch names.
