David Given 01a61e0708 Apply kernigh@'s fix to broken symbol tables in aelflod (via mailing list patch):
---snip---
The ELF spec at http://www.sco.com/developers/gabi/ says, "In each
symbol table, all symbols with STB_LOCAL binding precede the weak and
global symbols," and that sh_info is the index of the first non-local
symbol.

I was mixing local and global symbols and setting sh_info to zero. I
also forgot to set the type of the .shstrtab section.

George Koehler 5cf2a68438 Teach aelflod to write the ELF symbol table.
Convert each ack.out symbol to ELF, preserving its name and value, and
some but not all other symbol info.  The ELF symbol table comes with
ELF section headers.  If the input file has no symbols (ack -Rled-s),
then the output file has no ELF section headers.

Append the symbol table and section headers to the ELF file.  Linux
ignores this appended info when it execs the file.  The info might
pollute the last page of the ELF segment, but Linux clears this
pollution.  Tools like nm and gdb can read the ELF symbol table.

I include code to translate debugger symbols to an ELF .stab section.
I did not test this code, because I did not find a platform that can
put S_STB symbols in the ack.out file.

George Koehler c8fdcff960 Some fixes for aelflod and aslod.
Copy rhead() and rsect() from aslod to aelflod, so aelflod can work
for machine with 64-bit long.

In aelflod, fix ELF header so file(1) no longer reports "corrupted
section header size".

when reading the structure header.
