IIUC the problem is:

1) On ELF/GCC-compatible systems, GnuTLS author(s) wants to initialize the 
library
   with gnutls_global_init called from __attribute__((constructor)) function.
   Since gnutls_global_init uses memory allocation functions, any call to
   gnutls_global_set_mem_functions from an application is just too late.

2) Emacs' GnuTLS code doesn't care about GNUTLS_E_MEMORY_ERROR too much because
   we assume that the library can call our xmalloc and friends, where we 
actually
   handle errors in Emacs-specific way.

IMO the best approach is to review/fix src/gnutls.c to handle 
GNUTLS_E_MEMORY_ERROR
among other errors and don't interfere in the library itself in any way.
