[Linaro-validation] GCC build speed and backlog

The PandaBoard auto builders are having a hard time keeping with
longer build and test times of 4.7 and the re-enabled libstdc++ tests.
 For reference, here's how much each step costs:

Bootstrap GCC with C, C++, Fortran, and Obj-C: 9 hours
Test GCC: 9.5 hours
Test libstdc++: 4.4 hours
Test libgomp: 0.9 hours
Other tests: 0.2 hours

for a grand total of 23.8 hours.  Every new commit gives a merge
request and trunk build for both A9 and ARMv5 giving 95 hours of
compute time.  GCC 4.6 takes five hours to build and 5.5 to test.

This is just a FYI.  I'll think about ways of speeding things up or
adding capacity.  An i.MX6 with 2 GB of RAM and SATA would be nice...
