-SYNOPSIS
- struct elf_internal_shdr *bfd_elf_find_section (bfd *abfd, char *name);
-
-DESCRIPTION
- Helper functions for GDB to locate the string tables.
- Since BFD hides string tables from callers, GDB needs to use an
- internal hook to find them. Sun's .stabstr, in particular,
- isn't even pointed to by the .stab section, so ordinary
- mechanisms wouldn't work to find it, even if we had some.
