ee53977c97 Do all allocation and deallocation of shstr in elf_symload() to 
prevent double-freeing shstr.

Also don't free known NULL values (*pnames and *psnames).

Initially inspired by Charles Longeau's first diff to tech@; he
later sent a second diff to tech@ nearly identical to this commit.
Freaky.

OK mickey@.

e588d87f2a Some fixes for running nm on ELF binaries. 
- Fix printing the symbol type of undefined symbols.
- Fall back onto the dynamic symbol table if the normal symbol table is not
  available (i.e. if the binary has been stripped).

5b19ca8c08 move out elf code into elf.c and generate 32 and 64 versions of it; 
allow operation on size-mixed host-target as well as ensianess for
both a.out and elf (though a.out 64bit probably does not exist ;)

f1ba34738e Change all option list specifications to ".Bl -tag -width Ds". Most man 
pages just needed their -width parameter tweaked to "Ds", which provides
a nice width of 6 constant characters. For consistency more than anything.

070a3e5900 Fixes endianess problems with old a.out tools. This makes building 
some cross toolchains possible.

This also changes some utilities's behavior slightly:
- nm, strip, size now handle any a.out format they know about.
- ranlib complains if it detects mixed archives (several object
formats for different boxes).

In the presence of mixed objects, you still have file, ranlib or ld
to prevent you from getting too confused...
