Bernd Schmidt writes:
This reintroduces a mechanism identical to the DL_BOOT macro present in older versions of uClibc. On Blackfin and FRV, we want to pass more than one argument to _dl_start. We also want to do something special before returning, so delete the warning when the START macro is defined.
