    riscv: Enable -fasynchronous-unwind-tables by default on Linux

Broke several tests in the risc-v testsuite for riscv64-unknown-linux-gnu:

FAIL: gcc.target/riscv/shorten-memrefs-2.c   -Os   scan-assembler
store1a:\n\taddi
FAIL: gcc.target/riscv/shorten-memrefs-2.c   -Os   scan-assembler
load1r:\n\taddi
FAIL: gcc.target/riscv/shorten-memrefs-2.c   -Os   scan-assembler
load2r:\n\taddi
XPASS: gcc.target/riscv/shorten-memrefs-3.c   -Os   scan-assembler-not
load1a:\n\taddi
FAIL: gcc.target/riscv/shorten-memrefs-5.c   -Os   scan-assembler
store1a:\n\taddi

XPASS: gcc.target/riscv/shorten-memrefs-6.c   -Os   scan-assembler-not
load1a:\n\taddi
FAIL: gcc.target/riscv/shorten-memrefs-8.c   -Os   scan-assembler

FAIL: gcc.target/riscv/shorten-memrefs-8.c   -Os   scan-assembler
load:\n\taddi\ta[0-7],a[0-7],1


I'm pretty sure the change causes new labels to be inserted in places where=
 the
scan-assembler strings are not expecting to find them.=
