Subject: [PATCH] win32: build-tcc.bat: add some options

In particular:

-c <compiler> : Allow using tcc to compile itself
-i <dir>      : Create installation in dir

Summary:

usage: build-tcc.bat [ options ... ]
options:
  -c prog              use prog (gcc or tcc) to compile tcc
  -c "prog options"    use prog with options to compile tcc
  -t 32/64             force 32/64 bit default target
  -v "version"         set tcc version
  -i dir               install tcc into dir
  -d                   create tcc-doc.html too (needs makeinfo)
