GCC Spec File for Profiling

[Michael Casadevall <sonicmctails@gmail.com>]

After some trail and error as well as reading up how static binaries work 
and the difference between gcrt0 and gcrt1, I was able to fix the 
profiling bug with a GCC spec file:

%rename startfile old_startfile

*startfile: %{!shared: %{!static: %{pg:gcrt0.o%s} %{!pg:%{p:gcrt0.o%s} %{!p:crt1.o%s}}} %{static: %{pg:gcrt0.o%s} %{!pg:{%p:gcrt0}} %{!p:crt0.o%s}}} crti.o%s %{static:crtbeginT.o%s} %{!static:%{!shared:crtbegin.o%s} %{shared:crtbeginS.o%s}}

For those of you who know how Hurd handles statically linked binaries, 
you'll probably find it weird that we only link against gcrt0. The reason
behind that is that the profiling code in GCC only works against static 
binaries; it doesn't support shared binaries. This is my first time ever 
messing around with GCC (or writing a spec file) so I'd be intersted in 
hearing some feedback. I already figured out howto change GCCs internal 
specs file to include this change, but I wanted to hear from the experts 
before I submit a patch.
