build problems

[Brian Stephenson]

the problems I noted when I first got linuxbios up after christmas were:

1: burn_mtd script
2: command line wasn't getting thru to linuxbiosmain.c
3: mtd code not up to date in test12 kernel

1/ burn_mtd is fixed
2/ command line still not getting thru
3/ the problem with mtd was not a sync problem with mtd and test12 as I
    first thought but #define DOC_SINGLE in docprobe.c needs to be undefined

this might help someone
