The "pre-installed gcc" shouldn't come into play here, because you are
using an RTEMS cross-compiler, e.g., sparc5-rtems-gcc. My best guesses
for why you will see different results:
1. Different configure command line. I see libnetworking in your
build, probably Joel has --disable-networking
2. Different toolchain version. Make sure you build the toolchain to
match, in your case maybe it is master/master of rtems.git and
rtems-source-builder.git?
3. Different RTEMS version. Perhaps Joel's report is based on a
version of rtems earlier than yours. His build indiciates a date stamp
of April 8, and you build around April 29, so there is 3 weeks
difference in your versions maybe.
