Re: [FYI] {maint} testsuite: be more cross-compile friendly

[Stefano Lattarini]

It would also be nice to give the users/developers an hint on how to
force the use of cross-compilers in the testsuite at runtime; I've thus
applied, to the 'testsuite-work' branch, the two attached patches, the
first one of which updates `tests/README' appropriately w.r.t. cross
compiling issues, and the second one of which introduces a small
follow-up consistency change.

Regards,
  Stefano

Subject: [PATCH 1/2] tests/README: suggest how to run tests in cross-compile 
mode

* tests/README (Section "User interface" subsection "Running the
tests"): Briefly explain how to override 'host_alias' at runtime
to force the use of cross-compilers by the testsuite.  Give an
example.
