John Polstra ef431e2e9e Use "gcc -shared" instead of "ld -Bshareable" for building shared
libraries.  Remove the now-unneeded CPLUSPLUSLIB hack.  I will also
remove the CPLUSPLUSLIB definitions from the Makefiles that use it,
after the dust settles.

Use gcc's LIBRARY_PATH environment variable to handle DESTDIR,
instead of -L flags in LDDESTDIR.  LIBRARY_PATH is documented in
the gcc info pages.  It is better than using -L flags, because it
modifies the search for start-up files as well as for libraries.
A new variable LDDESTDIRENV is used to contain the normally-empty
LIBRARY_PATH environment setting.

LDDESTDIR is no longer set in <bsd.lib.mk>.  It is still honored for
the time being, because a couple of userland Makefiles still (wrongly)
set it.  These should be fixed, and LDDESTDIR should vanish.

Removed the commented-out "LDDESTDIR+=-nostdlib", because "gcc -shared"
doesn't link in any standard libraries anyway.

Removed the ".if defined(LDADD)" around the _EXTRADEPEND target for
shared libraries.  This target is always necessary now, because
c++rt0.o is linked into every shared library.

Don't merge this into -2.2 without first merging the support for
"gcc -shared".
