Add support for the RISC-V-specific ELF flags

Browse Source 
The RISC-V port defines ELF flags that enforce compatibility between
various objects.  This adds the shared support necessary for these
flags.

2018-01-25  Palmer Dabbelt  <palmer@sifive.com>

        * elf/cache.c (print_entry): Add FLAG_RISCV_FLOAT_ABI_SOFT and
        FLAG_RISCV_FLOAT_ABI_DOUBLE.
        * elf/elf.h (EF_RISCV_RVC): New define.
        (EF_RISCV_FLOAT_ABI): Likewise.
        (EF_RISCV_FLOAT_ABI_SOFT): Likewise.
        (EF_RISCV_FLOAT_ABI_SINGLE): Likewise.
        (EF_RISCV_FLOAT_ABI_DOUBLE): Likewise.
        (EF_RISCV_FLOAT_ABI_QUAD): Likewise.
        * sysdeps/generic/ldconfig.h (FLAG_RISCV_FLOAT_ABI_SOFT): New
        define.
        (FLAG_RISCV_FLOAT_ABI_DOUBLE): Likewise.
