   Log Message:
   g95: fix build on linux
   force passing asprintf test which is incorrectly not found due to FORTIFY
   pass LIBRARY_PATH so crtn.o and crti.o are found on Ubuntu & friends

   Note many reporters need to install g++-multilib as a package to overcome
   the errors they reported in the bugs (missing <sys/cdefs.h>)
