one more time -- getting embinux/android toolchain working under f11

since i made such a mess of this yesterday, i'll take the
opportunity to apologize for complaining about what i *thought* was
the embinux android toolchain and, now that i downloaded the correct
one, here's what little it took to get it working on fedora 11
preview.

  once i got the tarball
"arm-none-linux-gnueabi-cortex-core-v2.tar.bz2" and unloaded it on my
f11 x86_64 system, my first attempt to compile "hi, world" resulted in
an error looking for /lib/ld-linux.so.2, easily fixable by installing
the i686 version of glibc for 32-bit support:

  # yum install glibc.i686

the second error was because i installed the toolchain under my home
directory (to avoid needing root privilege), which produced this:

/home/rpjday/beagle/android/arm-none-linux-gnueabi/bin/../lib/gcc/arm-none-linux-gnueabi/4.2.3/../../../../arm-none-linux-gnueabi/bin/ld:
cannot find /opt/arm-none-linux-gnueabi/lib/libc.so.6 collect2: ld
returned 1 exit status

which suggests that that toolchain *must* be installed under /opt and
that it's not relocatable. so i moved it and managed to compile my
"hi, world". haven't tested the resulting executable but the
toolchain seems to work.

i'll take my victories where i can get them.
