[LinuxBIOS] [buildrom] some build errors

[Indrek Kruusa]

Two of them:

1) building filo as payload
Compressing the ELF payload with lzma...
make: error

- problem: the filo seems to be already compressed at this point
- solution: make a fix or uncompress filo in deploy/filo-payload.elf.lzma & 
make

2) linuxbios revision
- for norwitch target in config/platforms/norwich.conf:
LINUXBIOS_TAG=2376

Is it so badly wrong for the reason? :)

cheers,
Indrek
