Commit cb3d5f4eaee238e349e68bee34bde5764d94a3b0 in trafficserver's branch

TS-4047: consistently handle multiple RPATH options
Using TS_ADDTO to add the custom locations of libraries results in
incorrect "-rpath" directive to the linker. This is because TS_ADDTO
creates a unique list of tokens that it adds to its target.
e.g. ./configure --with-openssl=/usr/local/openssl --with-zlib=/usr/local/zlib
The above results in LIBTOOL_LINK_FLAGS:
-rpath /usr/local/openssl/lib /usr/local/zlib/lib
The absence of "-rpath" in front of the second path causes an error
in the linker. This is fixed by introducing a new macro TS_ADD_RPATH_TO
that takes a path and adds it with the "-R " prefix.
Also added the influential environmental variable RPATH that can
be used to give an additional value for the rpath.
This closes #324.
