Pinging again in the hope of getting the patch in, I'd like to have less outstanding patches :) (I have quite a few and new releases can become painful!)
gcc/ChangeLog config.gcc (arm*-*-netbsdelf*) Add support for EABI configuration config.host (arm*-*-netbsd*): Build driver-arm.o config/arm/netbsd-eabi.h: New file. config/arm/netbsd-elf.h config/netbsd-elf.h: Define SUBTARGET_EXTRA_SPECS. libgcc/ChangeLog config.host (arm*-*-netbsdelf*): Add support for EABI configuration config/arm/t-netbsd: LIB1ASMFUNCS: Append to existing set.
