Bugzilla Bug 83000

The net-nds/portmap Makefile contains the following snippet around line 110:

COPT    = $(CONST) -Dperror=xperror $(CHECK_PORT) \
        $(SYS) -DFACILITY=$(FACILITY) $(ULONG) $(ZOMBIES) $(SA_LEN) \
        $(LOOPBACK) $(SETPGRP)

If the user has the environment variable SYS set to anything besides whitespace, the compile bombs out. Examples:

I haven't seen any situation yet where it would be useful for a Gentoo Linux system to let the Makefile blindly pull this in from the environment, but I've encountered reports of this type of problem a few times already. So it would seem the default behavior should be changed to *not* pull in $(SYS) from the environment since it's a variable name likely to be used.
I think we should patch portmap's Makefile to either use a different name there, or to simply not use it at all. I'm not sure about the implications of not using SYS on a Solaris system, but since Portaris is very much under work I don't think it should be a blocker.

Reproducible: Always
Steps to Reproduce:
SYS="whatever" emerge net-nds/portmap
Actual Results:  
Compile fails with "cannot specify -o with -c or -S and multiple compilations"

I forgot an additional argument for patching it: The resulting errors give no
clue whatsoever to the typical user as to the root cause of the problem and to
what one should do to fix it. Tracking it down requires an unpack step and an
understanding on Makefile and compiler command line syntax. That's a no-no.

Patch renaming $(SYS)

This patch alters the Makefile usage of the environment variable SYS to
GLOCAL_SYS.

Patch to ebuild to use portmap-5b-renamesysvar.patch

deleted the variable all together since the makefile doesnt use it at all
