racket 6.3 build failures on armel
I'm stuck figuring out some build-failures on armel.
On the autobuilders, I get (twice, on two different autobuilders)
,----
| Copying /«PKGBUILDDIR»/collects/racket/private/kernstruct.rkt to /«PKGBUILDDIR»/build/racket/gc2/xform-collects/racket/private/kernstruct.rkt

| Copying /«PKGBUILDDIR»/collects/racket/private/top-int.rkt to internal error in JIT;
| ending address 0xb35bf650 not in [0xb35bf548,0xb35bf648] (0)
| internal error: JIT buffer overflow

There are several also a few warnings, I'm not sure if there is some
kind of architecture detection failure.

On the porterbox (abel.debian.org), I can't duplicate that failure, but
I get occasional (less than 1 build in 10) segfaults in racketcgc

Finally, once (out of about 25 builds), racketcgc was still running 9.5h
later, and ignoring SIGTERM. It was aparently processing char.c
