[PATCH][ARM][testsuite] add dg-timeout-factor to handle large tests

[Laurent GUERBY]

The following patch fix all 12 "WARNING: program timed out"
when bootstraping then running the testsuite on a 600 MHz ARM
arm-unknown-linux-gnueabi. Before and after:

http://gcc.gnu.org/ml/gcc-testresults/2009-01/msg00092.html
http://gcc.gnu.org/ml/gcc-testresults/2009-01/msg00294.html

I chose to use "dg-timeout-factor 4.0" and not to conditionalize on
platform since those particular tests are much longer than
others so this may help other platforms as well.

Ok to commit?
