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...
