gcc:
* config.gcc (arm*-*-netbsdelf*) Add support for EABI configuration.
* config.host (arm*-*-netbsd*): Use driver-arm.o on native NetBSD.
* config/arm/netbsd-eabi.h: New file.
* config/arm/netbsd-elf.h (TARGET_OS_CPP_BUILTINS): Undefine before
redefining.
(SUBTARGET_EXTRA_ASM_SPEC): Don't pass -matpcs to the assembler.
* config/netbsd-elf.h (NETBSD_LINK_LD_ELF_SO_SPEC): New define.
(NETBSD_SUBTARGET_EXTRA_SPECS): New define.
(SUBTARGET_EXTRA_SPECS): Define to NETBSD_SUBTARGET_EXTRA_SPECS.
libatomic:
* configure.tgt (arm*): Handle NetBSD in the same way as FreeBSD.
libgcc:
* config.host (arm*-*-netbsdelf*): Add support for EABI configurations.
* config/arm/t-netbsd (LIB1ASMFUNCS): Add some additional assembler
functions to build.
* config/arm/t-netbsd-eabi: New file.
