[Boost-build] How do I change the assembler rule?

Subject: [Boost-build] How do I change the assembler rule?
From: Kuhl, Brian (brian.kuhl_at_[hidden])

Hi,
I've added an additional compiler file for Wind River's Diab cross-compiler: boost_1_59_0/tools/src/tools/diab.jam
(I based it on the cray.jam in the same directory)
I can successfully compile most of boost with only a handful odd compiler issues.

But the assembler rule is all wrong, and I need to override it successfully compile "context",  the correct tool string is available in the shell as $(AR),
but I'm not sure how to write the jam syntax to propagate that, and override the default that seems to be coming from gcc.jam?

(Not sure why "context" is being built when the little summary says it won't be, but that's a separate issue?)
