sort out some nits with config/{*,}/darwin*.h and hack in a solution for
dsymtuil

The dsymutils issue is not a GCC bug - but it is a problem that gcc darwin
developers need to deal with in the short to medium term (possibly long-term
for darwin<10) ... 

OK, this is a patch which is work in progress to clean up darwin*.h:

(a) clear up some nits in the spacing of asm directives
(b) make sure that we only need to maintain one LINK_COMMAND_SPEC -

and ... now ... 
(c) provide a hack to get round the dsymtuils problem

this is NOT a proposed patch to solve the problem - but it is a patch to allow
things to proceed for developers without being inundated with error messages.

I've made the dsymutils produce flat files for the output (.dwarf) which seem
to work fine with the XCode gdb and avoid the "dSYM is a directory" config
warnings.

debug is working for fortran with this but ONLY if you put -save-temps on the
C/L .. dunno why that is yet.. (-pipe doesn't solve it).

-====-
Perhaps someone could look at how this can be packaged so that we can use it
for things like "regress"?
