 Now on i386-8.0_STABLE...
 
 As I had removed "mplayer" entirely, rather than replace, I performed
 a fresh "package-install" with the above modification to the package
 Makefile.  The resulting 'mplayer' now simply crashes with:
 
   $ mplayer
   mplayer: text relocations
   Memory fault (core dumped) 
 
 'gdb' shows:
 
 [...]
 Core was generated by `mplayer'.
 Program terminated with signal SIGSEGV, Segmentation fault.
 #0  0xbaff1790 in ?? ()
 (gdb) bt
 #0  0xbaff1790 in ?? ()
 #1  0xbb003000 in ?? ()
 Backtrace stopped: previous frame inner to this frame (corrupt stack?)
 
 I'll see about building with the "debug" option along with
 "INSTALL_UNSTRIPPED=yes" and "C{,XX}FLAGS+=-ggdb"
