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 Signed-off-by: Robert Schiele <rschiele@gmail.com> Signed-off-by: Alexander Sverdlin <alexander.sverdlin@nokia.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: "Maciej W.
