s390/vdso: Generate unwind information for C modules

Browse source

GDB fails to unwind vDSO functions with error message "PC not saved",
for instance when stepping through gettimeofday().

Add -fasynchronous-unwind-tables to CFLAGS to generate .eh_frame
DWARF unwind information for the vDSO C modules.
