I doubt there is anything wrong with it. The spec file discards the 
insight included readline as well as all the tcl-tk stuff and just uses 
the system versions. But I have always used insight's readline since I 
didn't know there was an alternative.

Yes, I tried that and it make rpm and srpm which installs and runs and 
"help" shows configured as target=arm-none-eabi as I entered in the spec 
file. The spec file seems to only use the --with-system-readline so it 
never sees the bug you ran into.

You can also get a pre-build gcc version from Mentor/Codesourcery that 
that includes all the source and giant build file that you may have to 
adjust to build all the tools: gcc, gdb, newlib etc. It doesn't include 
insight however since they have moved to using Eclipse.

This is how I typically configure w/o using the included tcl/tk. I think 
the various "--with-tcl=/usr/lib" may fix the error you see (may have to 
adjust the path).

../insight_sources/configure -v --quiet --prefix=$PREFIX \
    --target=arm-none-eabi --enable-interwork --enable-multilib \
    --with-gnu-ld --with-gnu-as --disable-werror \
    --with-tcl=/usr/lib --with-tk=/usr/lib --with-itcl=/usr/lib \
    --with-itclconfig=/usr/lib --with-itkconfig=/usr/lib
