Bug 150442

When compiling the port with gcc45 linker first tries to use gcc's own
-lstdc++ in LOCALBASE/lib/gcc45. But if you specify -L/usr/lib on
command line it'll use -lstdc++ from our ancient gcc42 in base.

IOW, let gcc decide where to search for it's own -lstdc++. And while
here remove -L/sw/lib as well, we don't have /sw in our hier(7).

How-To-Repeat: $ echo 'int main(void) { return(0); }' | g++45 -xc++ -o/dev/null - -Wl,--ve=
rbose |& fgrep -- -lstdc++
-lstdc++ (/usr/pkg/lib/gcc45/gcc/x86_64-portbld-freebsd9.0/4.5.2/../../../l=
ibstdc++.so)
$ realpath /usr/pkg/lib/gcc45/gcc/x86_64-portbld-freebsd9.0/4.5.2/../../../=
libstdc++.so
/usr/pkg/lib/gcc45/libstdc++.so.6
$ echo 'int main(void) { return(0); }' | g++45 -xc++ -o/dev/null - -Wl,--ve=
rbose -L/usr/lib |& fgrep -- -lstdc++
-lstdc++ (/usr/lib/libstdc++.so)
