[LV-tools-commit] toolchain/scripts build_toolchain.sh,1.18,1.19

[Jan-Benedict G. <jb...@us...>]

Update of /cvsroot/linux-vax/toolchain/scripts
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv23835

Modified Files:
	build_toolchain.sh 
Log Message:
- Install uClibc
- Fiddle a bit with symlinks to allow GCC to actually find the library
  as well as the matching header files.
- This results in a somewhat working userland compiler.
- exit(xx) is broken at the moment. crt1.S is supposed to push a function
  pointer (named rtld_fini) on the stack (to be passed to __uClibc_main()),
  but I don't know what it is supposed to be, so I just pushed 0x00000002,
  but that gets executed as a function pointer (and we crash, obviously).
- If you use _exit(), it'll work.
- I could push 0x00000000 instead (the value is checked to not be a NULL
  pointer before being referenced), but that wouldn't remind me that
  there's still a broken spot. So I prefer seeing the application crash
  instead.
