RISC-V: Add riscv{32,64}be with big endian as default
gcc/
* common/config/riscv/riscv-common.c
(TARGET_DEFAULT_TARGET_FLAGS): Set default endianness.
* config.gcc (riscv32be-*, riscv64be-*): Set
TARGET_BIG_ENDIAN_DEFAULT to 1.
* config/riscv/elf.h (LINK_SPEC): Change -melf* value
depending on default endianness.
* config/riscv/freebsd.h (LINK_SPEC): Likewise.
* config/riscv/linux.h (LINK_SPEC): Likewise.
* config/riscv/riscv.c (TARGET_DEFAULT_TARGET_FLAGS): Set
default endianness.
* config/riscv/riscv.h (DEFAULT_ENDIAN_SPEC): New macro.
