>Description:
With a very recent version of Clang (r192389), compilation of the databases/py-sqlite3 port fails:

/path/to/clang -shared -O2 -pipe -march=native -fno-strict-aliasing build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/cache.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/connection.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/cursor.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/microprotocols.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/module.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/prepare_protocol.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/row.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/statement.o build/temp.freebsd-11.0-CURRENT-i386-2.7/_sqlite/util.o -L/usr/local/lib -R/usr/local/lib -lsqlite3 -o build/lib.freebsd-11.0-CURRENT-i386-2.7/_sqlite3.so
clang: error: unknown argument: '-R/usr/local/lib'
error: command '/path/to/clang' failed with exit status 1
*** Error code 1

-R/usr/local/bin should have been -Wl,-R/usr/local/bin (or such an argument should not have been specified, or whatever). Previously, Clang gave only a warning, now it gives an error. Illustration:

$ r188103-clang -R/usr/local/bin somefile.c
clang: warning: argument unused during compilation: '-R/usr/local/bin'
$ echo $?
0

$ r192389-clang -R/usr/local/bin somefile.c
clang: error: unknown argument: '-R/usr/local/bin'
$ echo $?
1

>How-To-Repeat:
Check out, build and install Clang/LLVM r192389, and with that, try to build the port.
