Given an open bfd, a base address to relocate symbols to, and a
flag that specifies whether or not this bfd is for an executable
or not (may be shared library for example), add all the global
function and data symbols to the minimal symbol table.

/* Scan and build partial symbols for a symbol file.
We have been initialized by a call to som_symfile_init, which
currently does nothing.
SECTION_OFFSETS is a set of offsets to apply to relocate the symbols
in each section. This is ignored, as it isn't needed for SOM.
This function only does the minimum work necessary for letting the
user "name" things symbolically; it does not read the entire symtab.
Instead, it reads the external and static symbols and puts them in partial
symbol tables. When more extensive information is requested of a
file, the corresponding partial symbol table is mutated into a full
fledged symbol table by going back and reading the symbols
for real.
We look for sections with specific names, to tell us what debug
format to look for: FIXME!!!
somstab_build_psymtabs() handles STABS symbols.
Note that SOM files have a "minimal" symbol table, which is vaguely
reminiscent of a COFF symbol table, but has only the minimal information
necessary for linking. We process this also, and use the information to
build gdb's minimal symbol table. This gives us some minimal debugging
capability even for files compiled without -g. */
