Our current build systems can turn GCC 4.7 around in about 24 hours. The
enterprise hardware we anticipate using will take that down to about 12
hours. If speed of build hardware is a consideration, where do you draw the
line? No secondary arch is going to get to the speed of x86_64 in the
foreseeable future, so it's effectively a way to keep PA an exclusive x86
Well the solution seems rather obvious to me .
There is no real (technical) reason why you cannot build on x86_64
hardware. I never ever built anything on ARM directly using cross
compilers on an x86_64 host is orders of magnitude faster so I saw no
reason to attempt to build on ARM. The ARM hardware I worked with had
only 128MB of RAM and a 400Mhz CPU but the same should apply to modern
ARM platforms too (i.e building on x86_64 is just the saner way).
