  No.  Each C based module is stand alone, so the easiest thing is to remove
libtcc.so from the target 'all' (and maybe from the install target as well). 
Unfortunately, TCC [1] is a bit of a pain to get working, unfortunately.

  You might also have problems with org.conman.magic [2], but again, unless
you need to identify files programmically, you can ignore that one as well.

  -spc

[1]	It's a C compiler in a library.  I use it more for quick hacks than
	anything in production.  I can't even use it at work since it
	doesn't support the SPARC architecture.

[2]	It's the library behind the Unix program "file".  It identifies
	files based on embedded magic numbers.
