Hostboot build tools utilities are built as 32-bit

[jk-ozlabs]

Currently, the hostboot utils are built with -m32. For example:

g++ -m32  -c  -g -O0   -I ../../../../src/include/usr -I ../../../../obj/genfiles  -o ../../../../obj/modules/errl/parser/errlparser.o  errlparser.C

This means that 64-bit build machines need an entire 32-bit toolchain. We've worked-around this by requiring 32-bit libc and a multilib-capable compiler in the README, but it'd be nice not to require that.

but it'd be nice not to require that.

in fact, gcc-multilib can't be installed alongside the Ubuntu powerpc64le cross compiler. This means that we require two separate build environments for hostboot vs general LE Linux binaries.

I hope this isn't off topic, but a goal of mine (and others) is to build the open-power image on the system it runs on... i.e. Palmetto can be built by the OS running on a Palmetto. I suspect there will be some other changes to the build env to make it work. Keep the end goal in mind when coming up with any solution
