Massage build of linux-dwarffortress

 - change back from c6 to the default (c7 now)
 - don't install the bundled libc++, because it requires glibc 2.18
   which c7 doesn't have
 - avoid a runtime error message about sound-not-loading by switching
   off sound in the shipped config files. These are copied to the
   user's ~/.dwarffortress directory and can be edited there if needed.
