/*
* stubs for C-linkage library functions which we need to refer to
* from Lisp
*
* (But note this is only the Linux version, as per the FIXME
* note in the BSD version in undefineds.h.)
*
* These stubs exist for the benefit of Lisp code that needs to refer
* to foreign symbols when dlsym() is not available (i.e. when dumping
* cold-sbcl.core, when we may be running in a host that's not SBCL,
* or on platforms that don't have it at all). If the runtime is
* dynamically linked, library functions won't be linked into it, so
* the map file won't show them. So, we need a bunch of stubs that
* nm(1) _can_ see.
*/
