Fix updated for gcc 4.4.0, link xpg6 for c++, and link xpg4 for gnu*

Updated patch against gcc 4.4.0.
Also add xpg6 for c++ and xpg4 for gnu* as discussed above (this is now easily
modified by changing the spec if someone who knows better can say what gnu*
should do).

Proposed fix: Changes linking on solaris based on std=X and implements escapes
in braced specs

Attaching a fix that works here for Solaris 10 and I think would work for other
Solaris versions.
It changes the spec to account for the other options mentioned in comment 3, to
handle the main issue of the bug (link values-xpg6.o in c99 mode), and also
adds linking of values-xpg4.o as the Solaris manual suggests should be done.
I wasn't sure exactly how to handle the various -std=gnu* modes, so I left
those as they were. 

To enable matching on ':' in std=iso9899:, I had to augment the spec
language, as suggested in comment 6.  I realize you might want to treat this as
a separate issue -- I can open a separate issue for this if you want.

Was looking at modifying the spec to produce the desired results and contribute
patch, however ran into trouble trying to match options containing literal
colons (-std=iso9899:199409) in %{S:X} style spec.

Is there a way in the spec language to escape colons?  I briefly scanned the
spec parsing code and nothing jumped out.

If not, is there some other way to match options containing colons (without
using greedy * matches, since the part after the colon is significant here...)

This also applies to Solaris x86.

Additionally, this only applies to Solaris 10 and later. Earlier versions of
Solaris did not ship c99-compliant C library and thus do not have the
values-xpg6.o object file for enabling c99-compliance.

[Bug c/40411] New: -std=c99 does not enable c99 mode in Solaris C library

[heydowns at borg dot com]

On Solaris, the C library does not operate in c99 compliant mode by default. 
If c99 compliant operation is desired, the object file
/usr/lib/{32,64}/values-xpg6.o needs to be linked.  The details are in the
Solaris standards(5) manpage.

When linking using gcc -std=c99, gcc does not instruct the linker to include
this object file.
