            Bug ID: 221803
           Summary: ftp/rexx-curl: port passes $LDFLAGS to direct linker
                    invocation, not compiler driver

I've been investigating the state of the ports tree with LLVM's lld installed
as /usr/bin/ld (from the exp-run in PR 214864).

Normally LDFLAGS contains flags passed to the compiler driver when invoked for
linking. One issue that affects a small number of ports is passing $LDFLAGS to
direct linker invocation (i.e, $LD), where it contains flags that are
appropriate only for the compiler driver, not the linker.

In several instances this comes from bsd.ssp.mk, which adds -fstack-protector
to LDFLAGS.  GNU BFD ld accepts the flag but produces undesired output, while
lld produces an error:

ld -fstack-protector -shared -o libcfg+.so.0 ../src/cfg+.o ../src/parse.o
../src/props.o ../src/cmdline.o ../src/cfgfile.o ../src/shared.o
../src/platon/str/strplus.o ../src/platon/str/strctype.o
../src/platon/str/strdyn.o ../src/platon/str/dynfgets.o
ld: error: unknown argument: -fstack-protector
(from devel/libcfg)

(GNU ld produces output with a bogus DT_AUXILIARY "stack-protector" entry for
this case.)

This affects at least the following ports:
www/mod_jk
devel/libcfg
arabic/libitl
www/tdom
www/dummyflash
ftp/rexx-curl

ftp/rexx-curl build log excerpt when linking with lld:
ld -Bdynamic -Bshareable   -fstack-protector  -fstack-protector  -o
librexxcurl.so rexxcurl.so.o rxpack.so.o rxmt_posix.so.o -L/usr/local/lib
-lcurl -L/usr/local/lib -lregina   -lm
ld: error: unknown argument: -fstack-protector
ld: error: unknown argument: -fstack-protector
