emsource does not pass -a to emdebuild

[David Goodenough <david.goodenough@btconnect.com>]

When emsource invokes emdebuild, it does not pass any explicit
architecture to emdebuild using -a.  This means that you can only
build for the default target.

I am not sure that putting -a $arch on all the emdebuild is enough as
when I produced a local version of emsource which did pass it, emdebuild
failed complaining about files in /usr/bin being for the wrong architecture.
But that is for tomorrow morning to investigate.

Could this be because the build dependancies are installed using 
apt-get (which will get for the host architecture) rather than apt-cross?
