[distcc] getloadavg not completely portable...

[Jay 'Whip' Grizzard]

distcc 2.11.2 cannot build the gnome monitor under Solaris 2.6, because
the getloadavg(3) call doesn't yet exist in Solaris in that release, and
there's no option in the soruce for conditional compilation. 

[
So when linking, you get:

  src/mon-gnome.o(.text+0x4e4): In function `dcc_gnome_load_update_cb':
  : undefined reference to `getloadavg'
  collect2: ld returned 1 exit status
]

Prob'ly want to make that conditional.

Cheers.
