crash: build failure on RISC-V

[Heinrich Schuchardt]

version: 7.3.0-1ubuntu1

Building crash for RISC-V fails with a segfault. This segfault is due to missing support for architecture RISC-V in file configure.c. configure is used to update Makefile. It replaces "TARGET " by "(NULL)". A patch is at https://github.com/xypron/crash/commit/2391175c7936a3d873b7b7f1b6c6cae2f4c166b8

Current upstream crash uses an version 7.6 for gdb which does not support RISC-V. Patch series https://listman.redhat.com/archives/crash-utility/2021-March/msg00078.html provides an update to gdb 10.1.

https://github.com/YustasSwamp/crash/tree/crash-gdb10.2-devel-temp provides patches for using gdb 10.2.

For building we need command makeinfo which is provided by missing package texinfo.

makeinfo is provided in universe.

Additionally to adjusting configure.c the following changes to the upstream source are needed:

Add RISC-V to defs.h
Create riscv64.c, unwind_riscv64.c

The upstream issue for RISC-V support is https://github.com/crash-utility/crash/issues/89
