Some linker options were not prefixed by -Wl, when using gcc:

Using macro linkerprefix is fixing it.

Agree with Olivier, what exactly is the problem here?
When using CC as LD, linker options should be prefixed with -Wl.
Also, I don't think
this is correct, as CPU_LD_FLAGS and -z muldefs below is used in
conjunction with $LD.  It would make sense to prefix -Wl to these options
if we were passing them through $CC, but not $LD
Yes, but options are prefixed only in the case LD = CC.

Neil, this situation is funny as you're the author of the patch making LD as 
CC and you submitted this kind of fix to prefix CPU_LDFLAGS :)
This patch is a translation of yours with use of macro linkerprefix.

ah, sorry, was looking at the wrong clause in rte.lib.mk

Yeah, my fault, I was only looking at the lines changed, rather than the context
surrounding them.  This makes sense.
