#### Builders ####
##################
## This section describes our builders. The builders are instances of
## a build factory, and they will be used to do a specific build of
## the project.
##
## The nomenclature here is important. Every builder should start
## with the prefix "RunTestGDB", and then be followed by the testing
## scenario that the build will test, followed by "_cXXtYY", where XX
## is the bitness of the compilation, and YY is the bitness of the
## testing. So, for example, if we are specifically testing GDB
## running the native-gdbserver tests, compiling GDB on a 64-bit
## machine, but running the tests in 32-bit mode, our builder would be called:
