       [#1] The placement of a storage-class specifier  other  than
       at   the  beginning  of  the  declaration  specifiers  in  a
       declaration is an obsolescent feature.

71a4269193 Use -nodefaultlibs instead of -nostdlib when linking libc and libgcc* 
so that we still link in the crt* start/end files.
Explicitly link libc against gcc_pic, since -nodefaultlibs undoes this.

Fixes problems where shared libraries don't get init/fini sections,
most easily noticable with pthreads programs not working.

104cf0ae89 Add support for kernel preeemption to the i386 and amd64 ports. Notes: 
- I have seen one isolated panic in the x86 pmap, but otherwise i386
  seems stable with preemption enabled.

- amd64 is missing the FPU handling changes and it's not yet safe to
  enable it there.

- The usual level for kern.sched.kpreempt_pri will be 128 once enabled
  by default. For testing, setting it to 0 helps to shake out bugs.

Add an additional argument to pnpbus_intr_establish to allow overriding of
the pnp interrupt type, because some devices lie.
Change how the pnpbus match routine works, to avoid attaching it when we
are probing for cpu's.
Fix a few stray printf's in the autoconf output.
