GDB SIGSEGV opening a Fortran program compiled with ifort

Browse Source 
This patch fixes a SIGSEGV when trying to open a Fortran program
compiled with ifort (reproduced using version using version 16.0.1.150).
The error can be reproduce with most, if not any program. For instance,
a single file only containing "end", compiled with no additional flag,
suffices.

       * dwarf2read.c (read_partial_die): Do not call set_objfile_main_name
       if the function has no name.
