Bug#284793: libc6-prof: Running programs compiled with -profile fails

[Matthias Klose <doko@cs.tu-berlin.de>]

severity 284793 minor
reassign 284793 gcc
thanks

the -profile option isn't recognized. please use -p or --profile. in
earlier gcc versions, -profile did link in the gcrt0 start file, but
gcc-3.3 and later link crt0. I didn't any documentation actually
mentioning -profile.
