'/') given to -L to run-time library search path passed to the
lower linker using -Wl,-rpath=
This is a problem, because even if we add the right directory with
-Wl,-rpath= or variants thereof, the wrong path still is in the
RPATH on the resulting binary. This might lead to the wrong library
being found at run-time.
To build clean packages when using ocamlmklib, '-elfmode' will switch
this behaviour off; when using '-elfmode', all following -L parameters
won't augment the RPATH, and it has to be updated seperately with
-dllpath, -Wl,-rpath= etc.
(This is a local pkgsrc stopgap addition, needed to proceed with
fixes to xentools41. The issue has been raised with upstream;
hopefully this patch can be reverted with a future ocaml package
version.)
