[MiNT] rindex cleanup

[Vincent Rivière <vincent.riviere@freesbee.fr>]

Hello.

The attached patch for the MiNTLib defines the rindex alias for strrchr in a 
more portable way.

Actually, this is the only change required to successfully compile the 
MiNTLib using the ELF object file format ;-)

Please commit it using the following comment:
