New Revision: 16549

Log:
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.
