            Bug ID: 196493
           Summary: bsd.gcc.mk does not over-ride linking with gcc libs in
                    /usr/lib
           Product: Ports & Packages
           Version: Latest
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Ports Framework
          Assignee: freebsd-ports-bugs@FreeBSD.org

diff -u patch to change CFLAGS, CXXFLAGS, and LDFLAGS in bsd.gcc.mk.

System this was noticed on is FreeBSD 9.3 amd64, that has been upgraded to 9.3.
While researching build errors for net/freerdp, noticed that the build was not
linking with the libstdc++.so.6 in the /usr/local/lib tree, but was instead
trying to link with /usr/lib/libstdc++.so.6.

Think the root cause is the various ??FLAGS variables in
/usr/ports/Mk/bsd.gcc.mk are set by appending to the variables. Appending
causes what ever values are assigned to the ??FLAGS variables before bsd.gcc.mk
is evaluated to over-ride values set by bsd.gcc.mk.
