uClibc supports rindex if either of
* UCLIBC_SUSV3_LEGACY or
* UCLIBC_SYSV3_LEGACY MACROS
Previously UCLIBC_SUSV3_LEGACY_MACROS was defined,
but Bernhard wants to get rid of all legacy stuff, and his idea to achieve
this it is by intentionally breaking the build if you enable a package
containing SUSV3_LEGACY stuff.
