I'm mostly buliding in two steps:

  build=i686-linux, host=i686-linux, target=vax-linux-uclibc

And then, using the result of the above compilation run, I'm building

  build=i686-linux, host=vax-linux-uclibc, target=vax-linux-uclibc

The build process breaks while configuring GCC in the second run, when
I'm about to configure the vax-linux-uclibc hosted compiler. Both libs
are installed on my i686-linux machine, but there's of course not yet
a vax version on that machine.  Is it possible to just extract the two
lib's sources into GCC source tree for configure to find and build
them? (I'll try that right now, but a hint would be good to save me
some hours to wait for the compilation result.)

Thanks, JBG
