[oe] SDK problems. GCC won't launch because it can't find libmpfr.so.4

[Tasslehoff Kjappfot]

  I've compiled an SDK from a source tree in 
//data/src/lead-dev/openembedded/, and the resulting gcc compiler for 
arm has an RPATH of 
//data/src/lead-dev/openembedded/build/angstrom-dev/sysroots/i686-linux/usr/lib/, 
and will only run on my machine as long as that directory exists. If I 
remove that directory, it complains about libmpfr.so.4 not being found.

The previous SDK I built also had this odd RPATH, but gcc would run on 
other systems even if the RPATH-directory didn't exist.

I have placed the toolchain in a custom location and compile small 
applications with makefiles pointing to it. I tried unpacking to 
/usr/local/angstrom instead and ran the environment setup script, but 
got the same error.
