For executables, iterate through the sections to find out
which contains the symbol's address rather than using the
symbol_info field. (symbol_info has a different meaning for
dynamicly linked executables.)
subspaces too when writing executables. Never request a negative
bss size. Fixes some problems with demand paged executables,
still having problems with pure executables and shared executables.
containing all the private section information which needs
to be copied from input section to output section during
objcopy or strip.
(som_section_data_struct): Remove several fields now in
som_copyable_section_data_struct. Make the space and
subspace dictionaries be pointers (to save space when
only reading objects).

(som_write_armap): Initialize the checksum to zero.
(ar_maxchars): Fix. Opps.
elf32-hppa.c, elf32-mips.c, linker.c, som.c, sunos.c: If malloc(0)
returns NULL, it is not an error. It's possible that some of
these checks are not necessary (because the size can never be
zero), but putting in the checks is the conservative thing to do
in light of the fact that some of these malloc calls replaced
unchecked alloca calls, in which a zero argument would work fine.

munge section symbol names anymore -- they no longer confuse GDB.
(som_begin_writing): Leave space for an exec header if writing
an executable.
(som_slurp_symbol_table): Recognize both forms of section symbol
names "L$0\002" and "$<FOO>$". Change the name of "L$0\002"

(make_unique_section): Delete function. BFD and its users are
prepared to handle multiple sections with the same name.
(setup_sections): Allocate space on the BFD's obstack to hold
section names. Use bfd_make_setion_anyway rather than the
obsolete make_unique_section.

PARAMize and staticize rest of functions. Delete unused
functions. Delete unused/unnecessary arguments to some functions.
Group static vars together. Abort for bad errors until we have
error code propogation working. Work on spacing and indention.
Add FIXMEs for unresolved problems. Use enums rather than

Add FIXMEs for some unresolved problems. Delete hopelessly broken
COMPLEX relocation support (it's never used anyway).
