Patch to merge (most of) elfos.h and svr4.h

Hi Guys,
Whilst working on another problem I noticed that the files
gcc/config/elfos.h and gcc/config/svr4.h contain an awful lot of
duplicated definitions. Since this seemed to me to be both
redundant and error prone I decided to try to eliminate this feature
and the patch below does this.
Most of this patch is just a reformatting and rearrangment of the
two header files. I basically added a #include "elfos.h" to svr4.h
and then eliminated the duplicate definitions from the latter file.
There are a couple of points however that are worth mentioning:
* Several of the macros in elfos.h that generated .section
directives did so without prefixing them with a tab. I have
changed this so that a tab is always used.
* The SELECT_SECTION macro in elfos.h included some extra code to
detect if flag_pic was set, and if so, to select the data
section. This code was not present in the same version of the
macro in svr4.h, but I have assumed that leaving it in will not be
a problem for targets that include svr4.h.
* The macro UNIQUE_SECTION has been updated to handle the case
where it is called for uninitialised data. Although this would
not happen wih the current gcc sources I am also working on a
different patch which would have this effect. It seemed
reasonable to include this change here, since the macro was
already being rewritten.
Are there any objections to my applying this patch ?
Cheers
Nick

* config/elfos.h: Tidy up formatting of marcos. Make sure
that .section directives are always prefixed by a tab.
* config/svr4.h: Add #include "elfos.h" and remove duplicate
definitions.
