MIPS: VDSO: Explicitly use -fno-asynchronous-unwind-tables
Not every toolchain has -fno-asynchronous-unwind-tables per default on
MIPS. This patch specifies the necessary option explicitly for VDSO
library build.
This prevents the following build failure:
GENVDSO arch/mips/vdso/vdso-image.c
arch/mips/vdso/genvdso: 'arch/mips/vdso/vdso.so.dbg' contains relocation sections
.../arch/mips/vdso/Makefile:84: recipe for target 'arch/mips/vdso/vdso-image.c' failed
