* Patched gcc so that it doesn't search the standard include directories

(/usr/include, /usr/local/include, etc.).

* Immediate pay-off: we see that the glibc header files depend on the Linux
  kernel header files.  So I've added a package that extracts the appropriate
  headers from Linux 2.4.22.
