 Need to fix binutils... from src/libexec/ld.elf_so/rtld.c

      342 #if !defined(__arm__) && !defined(__mips__) && !defined(__sh__)
      343     /* ARM, MIPS and SH{3,5} have a bogus DT_TEXTREL. */

 Actually, this is a different (and fixed?) old bug.

 There is an incorrect DT_TEXTREL in libstdc++

 ...bin/ld: warning: dynamic relocation to `__gxx_personality_v0' in 
 readonly section `.eh_frame'

 which is coming from eh_personality.cc

 I've tracked the problem down to config.gcc where arm/arm.h needs to be 
 last so that
 the ARM_TARGET2_DWARF_FORMAT define in netbsd-eabi.h is seen

 I'm testing a fix
