package/uclibc: drop old SPARC symbols

BR2_sparc_v7 was removed in 2013 in commit '16bcf46a63 arch/sparc: drop
old SUN-specific variants'.

BR2_sparc_sparchfleon and BR2_sparc_sparchfleonv8 were moved to legacy
handling in 2014 in commit '43b78e7285 arch: sparc: Add leon3 cpu type
and remove sparc{s,h}fleon{,v8}' and later removed from legacy handling
in 2020.

So drop the remaining references for these symbols.
