 That would be strange of Apple, obviously they would know Rosetta existed
 and 10.6.8 (canonical one) supported building for `ppc`. But I will look
 into the code.

 GNU `libtool` at least in principle appears to be aware of building for
 `ppc` on 10.6, `config.guess` has:
 {{{
             # On 10.4-10.6 one might compile for PowerPC via gcc -arch ppc
             if (echo '#ifdef __POWERPC__'; echo IS_PPC; echo '#endif') | \
                    (CCOPTS="" $CC_FOR_BUILD -E - 2>/dev/null) | \
                    grep IS_PPC >/dev/null
             then
                 UNAME_PROCESSOR=powerpc
             fi
 }}}
