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".
