[Crash-utility] [PATCH] Fix build failure due to no EM_RISCV with glibc-2.23 and earlier
With glibc-2.23 and earlier (e.g. RHEL7), crash build fails with errors
like this due to EM_RISCV undeclared:
$ make -j 24 warn
TARGET: X86_64
CRASH: 8.0.2++
GDB: 10.2
...
symbols.c: In function 'is_kernel':
symbols.c:3746:8: error: 'EM_RISCV' undeclared (first use in this function)
case EM_RISCV:
^
...
Define EM_RISCV as 243 [1][2] if not defined.
