[committed] Fix mipsisa32-linux-gnu linker failures

[Richard Sandiford]

Alan's nod in the direction of mipsisa32-linux-gnu made me look at
the 3 linker failures there.  They were caused by missing checks for
$has_newabi.

These tests passed on mipsel-linux-gnu because of the default
"from-abi" architecture.  One fix would therefore have been to
force the architecture on the command line.  I think it's better
to test with the default architecture where possible though,
so we'd need some machinery to conditionally add an architecture
option only when one was needed.

In the meantime, this patch makes the handling of these three
tests consistent with all the other NewABI tests.  Tested on
mipsisa32-linux-gnu and applied.
