Why are you choosing those flags?

Probably because they are advertised on: http://gcc.gnu.org/install/specific.html#sparc64-x-solaris2

Just do CC=cc, you will get both a 32-bit and a 64-bit compiler. What seems to be happening is that the build process assumes that the first libiberty you get (the one built with the native compiler) is 32-bit code.

Douglas has simply mixed 32-bit and 64-bit configuration.

For the 32-bit compiler (sparc-sun-solaris2.9), CC=cc is fine. For the 64-bit compiler (sparc64-sun-solaris2.9), CC="cc -xarch=v9" is fine.

This seems error-prone; maybe more warnings need to be added to the installation note.

Also, sparc-sun-solaris2.9 doesn't mean "32-bit compiler", it means "build both compilers, defaulting to 32 bits".
