Hmm, this is beginning to be really funny. My gentoo arm system has "#define

BFD_ARCH_SIZE 64" line in /usr/include/bfd.h, resulting in 64-bit vma typedefs.

I guess such weird configuration is a prerequisite for triggering this

alignment issue. The culprit is gentoo toolchain-binutils.eclass which is

forcing --enable-64-bit-bfd configure option. The architectures like ARM surely

have lots of spare RAM to waste... Looks like at least this part of the problem

needs to be solved on gentoo side.
