Comment (by bradleyCPA):

 The default alignment should be 12 (2^12 is 4096) not 11 (2^11 is 2048).
 This is why artifacts on my system such as:
 {{{
 otool -f /opt/local/lib/libgcc/libgcc_s.1.dylib
 Fat headers
 fat_magic 0xcafebabe
 nfat_arch 1
 architecture 0
     cputype 7
     cpusubtype 3
     capabilities 0x0
     offset 2048
     size 99832
     align 2^11 (2048)

 }}}
 are aligned as they are. Fat libraries aligned at 2048 do not load
 properly in tests on my system.
