[PATCH] apply -rpath option when running install_name_tool

[felix . winkelmann]

Hi!

This patch ensures that any runtime-linker path is specified with the "-rpath"
option in csc, then it is used when invoking "install_name_tool" to modify
the runtime path in produced executables. Other platforms use "-Wl,-rpath"
or similar, but on Mac OS this is done via said tool.

This also caused problems when running "make check" on Macs with an old
installation still in the install-prefix: csc would invoke install_name_tool 
with
the default prefix and thus any installed libchicken would be picked (instead
of the new one just built). On Linux LD_LIBRARY_PATH takes care of that
(and rpaths are not set by default).


cheers,
felix
