[committed] testsuite: Save dg-do-what-default in mve.exp

[Richard Sandiford]

mve.exp changed the default dg-do action to "assemble", but then
left it like that for later exp files.  This meant that in a
two-multilib test run, the first arm.exp run would have a default
of "dg-do compile" and the second would have a default of
"dg-do assemble".

Tested on arm-linux-gnueabihf and armeb-eabi.  Pushed as obvious.
