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".

3dcc3bd1cf Allow pc86 bootloader to boot from more floppy drives. 
When the bootloader probes the drive geometry, the BIOS can clobber the
es register.  If this happens, the bootloader loads the program to the
wrong address, and jumps off the code.  This happens with an emulated
floppy drive in Bochs or QEMU, but not with an emulated hard disk.
