Carl-Daniel Hailfinger e5fcf247f2 gcc -fwhole-program needs to mark any function which is used outside the 
current compilation unit to be marked as externally_visible. We have
EXPORT_SYMBOL exactly for that purpose.

This applies to the following symbols used by x86emu and/or vm86:
- pci_read_config8
- pci_read_config16
- pci_read_config32
- pci_write_config8
- pci_write_config16
- pci_write_config32
- dev_find_pci_device
- dev_find_slot
It also applies to the main entry point of stage2:
- stage2

With this patch, I can use -fwhole-program for stage2 without any
problems. For standard compilation, this is a noop.
