Merge branch 'kirr/tcc-MD' into mob

Hello up there.

I'm trying to change gcc to tcc for faster develpment on slow machines,
and the first obstacle that turned out was lack of dependency generation
on tcc side.

Attached patches try to fix that.

Thanks,
Kirill

* tcc-MD:
  .gitignore += tags
  tcc: Explicitly require -l<lib> for libraries
  Document what tcc_fileextension does
  tcc -E: Let output_default be <file>.o instead of a.out
  tcc: Draft suppoprt for -MD/-MF options
  tcc: Refactor "compute default outfile name" into libtcc function
  Add input files/libs and reloc_output switch to TCCState
  tcc: Fix typo in error (it's '%s', not '%s)
  chmod a-x i386-gen.c
  .gitignore += *.o *.a
  .cvsignore -> .gitignore
