dev-libs/libaio: link against stdlib to pull the fortified functions #558406

When '-fstack-protector-strong' is included in CFLAGS, the function
'__stack_chk_fail_local' needs to be pulled from libc. However,
upstream uses '-nostdlib' to avoid linking against any C library or
gcc libs. Remove '-nostdlib' and '-nostartfiles' to pull the required
symbols from libc.
