Assign to toolchain@, and thus, remove the now-redundant tag.

This is because 11.2 and 12.0 i386 are still on BFD ld 2.17.50, which neither supports LTO, nor plugins.  It's probably best to leave off -flto for these platforms, otherwise use lld or the binutils port.

  databases/couchdb3: accommodate compiler quirks in i386

  As reported in BZ, -flto passes unsupported parameters to /usr/bin/ld
