RISC-V: Error for relaxable branch in absolute section.
Emit an error instead of crashing in frag_new, handling this same as the
i386 port.
gas/
PR 26400
* config/tc-riscv.c (append_insn): If in absolute section, emit
error before add_relaxed_insn call.
* testsuite/gas/riscv/absolute-sec.d: New.
* testsuite/gas/riscv/absolute-sec.l: New.
* testsuite/gas/riscv/absolute-sec.s: New.
