New description:

 There is proposed "fix" for 10.5 SDK here: wiki:LeopardSDKFixes

 It is problematic, however: libgcc_s.10.5.dylib on 10.5.8 has 4 archs
 (including ppc64), while libgcc_s.10.5.dylib in 10.6 SDK from Xcode 4 has
 3 archs (no ppc64).

 Original file vs one extracted from Xcode:

Comment (by ryandesign):

 Then I guess you can't use that fix if you need ppc64. If you'd like to
 edit the wiki page to add a note to that effect, feel free.
