make O=directory parameter

[Fred 1]

like in the linux kernel build

make O=builds/arm

builds the result to the specified output directory


is this supposed to work for uboot also ?

doesn't seem to work for me, i've fetched older tar files and same problem

maybe my environment?

     fedora32

     5.10.13-100.fc32.x86_64

     GNU Make 4.2.1

the O=<dir>  does mostly work on older uboot like from ~2010 though....


thought i'd ask as debugging the make process is,well umm...horrible,

(i've inserted some extra debug print codes in gnu make (it self no code 
to be praised about!

esp when so much open source depends on it!!)

so atm, a bit of a rabbit hole........should I persist?
