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

2018-01-13  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.


This patch is OK, please commit.


Thanks.  Committed!


note that the FLAG_RISCV_FLOAT_ABI_SOFT ldconfig.h macro
value conflicts with the arm/ilp32 branch, i can update this
in the ilp32 branch but ldconfig will print existing ilp32
ld.so.cache files incorrectly.

Oh, sorry about that. I don't mind changing our flag value, what should I makeit?
