[Buildroot] Error: duplicate .personality directive while building libstdc++ w/ ARM EABI

[Jon Nalley <buildroot@nalleynet.com>]

All,

I have been attempting to produce an ARM EABI toolchain (including g++)
using the buildroot.  The build fails while building libstdc++ with the
error "duplicate .personality directive".  I did some googling and it
looks like this is coming from gas from binutils.  Although the build
fails to create libstdc++ it does successfully build gcc and I have
verified that gcc produces EABI binaries.  I have also verified that if
I disable EABI (and change the GNU target suffix to linux-uclibc) in the
buildroot config that the c++ compiler along with everything else
successfully builds.

Does anyone know why enabling EABI would prevent libstdc++ from
building?

I have selected the following in the Buildroot Configuration:

Target Architecture (armeb)
Target Architecture Variant (xscale)
Target ABI (EABI)
GNU target suffix (linux-uclibcgnueabi)
Binutils Version (binutils 2.17.50.0.16)
GCC compiler Version (gcc 4.1.2)
Build/install c++ compiler and libstdc++ (y)

More context for the error is attached below.

Any ideas on this issue are greatly appreciated.

Thanks,

Jon Nalley
