Problem building tools for 4.10 on F12 system

I'm building the tools using a 4.10.0 CVS fetch and the files in on an up-to-date Fedora 12 system.  I'm basing this on the web page as well as notes I kept when I last did this last April.  This is to build a multilib with SPE support, I haven't gotten that far yet, I'm just trying to reproduce what's shipped.

The problem is that GMP doesn't configure properly without a bit of magic I don't understand.

The first sign that there was going to be a problem was when I went to "rpmbuild" gcc:
rpmbuild -ba rtems-4.10-powerpc-rtems4.10-gcc.spec --target=1686-pc-linux-gnu
Building target platforms: 1686-pc-linux-gnu
Building for target 1686-pc-linux-gnu
sh: line 0: fg: no job control
error: File /opt/rtems/src/SOURCES/gmp-4.3.2.tar.bz2: No such file or directory

1. I don't know where that "no job control" message is coming from.  Running "sh" by itself doesn't give that warning.  I can't find "fg" in any of my .rc files (I use bash).
2. Why do I need to download gmp if it wasn't on the RTEMS FTP site?  Is that something that's missing?  Is F12 too old?

I downloaded gmp-4.3.2.tar.bz2 and put it where rpmbuild wanted it, and I got an error when gmp was configured (I left it out, but the "fg" message was still there):
Configuring in ./gmp
configure: creating cache ./config.cache

error: Bad exit status from /tmp/rtems/rpm-tmp.cn7Ybg (%build)

RPM build errors:
    Bad exit status from /tmp/rtems/rpm-tmp.cn7Ybg (%build)

Now the weird part: to see if I could get more info I ran "sh /tmp/rtemsrpm-tmp.cn7Ybg" and not only didn't I get the "fg" warning, but it went ahead and configured and built GMP, and it's well into building everything, it's been running for 45 minutes now.  I had done the "rpmbuild" several times already, so directly using "sh" is definitely a clue.

I unset most of my environment variables before starting the build.

Any ideas?
