Well, I also noticed a problem with this, and while I don't have a
solution, I do at least have another data point:

_OPSYS_RPATH_NAME is used in several ways.  On the one hand, it's used
to specify the flags to the *compiler* which flags are to be passed on
to the linker, ie '-Wl,${_OPSYS_RPATH_NAME}'.  In this instance, the
correct flags for MIPSPro compilers would be '-Wl,-rpath,/path'.
Setting _OPSYS_RPATH_NAME to "-rpath " would not work, in this scenario
(nor did using two '-Wl' flags (as "-Wl,-rpath -Wl,/path"), which is why
we set _OPSYS_RPATH_NAME to "-rpath," for Irix to begin with).

The problem occurs if we are not calling the compiler but the linker
directly.  The "-Wl,foo,bar" should be turned into "-foo bar" for the
linker, but we end up with "-foo,bar".

Buildlink3's ld-post-logic should take care of this.  Oddly, though, it
doesn't.  I had had to add the diff below to make this work:
