Add VxWorks options from specs to vxworks.opt

[Joseph S. Myers]

In preparation for the driver only accepting options listed in .opt
files, and not other options that simply happen to match some spec,
this patch adds VxWorks options matched by specs in vxworks.h to
vxworks.opt.  None of the options are matched by specs in vxworksae.h
and so Condition settings are used as for the other options in
vxworks.opt.

Note that before this patch -Bdynamic and -Bstatic would have added
various search paths based on the strings "dynamic" and "static" in
addition to having the effects from specs passing them to the linker.
Now they will only have the effects from specs, without also being
handled as -B options; this seems in accord with the intended
semantics as I interpret them.

Tested building cc1 and xgcc for crosses to: arm-wrs-vxworks
i686-wrs-vxworks i686-wrs-vxworksae mips-wrs-vxworks
powerpc-wrs-vxworks powerpc-wrs-vxworksae sh-wrs-vxworks
sparc-wrs-vxworks.  OK to commit?
